Top producer RedOne has had hits with dozens of artists, but relies on one man to "finish” tracks like Nicki Minaj's 'Starships': engineer Trevor Muzzy.
In recent years, Nadir Khayat, aka RedOne, has been involved in the writing and production of several dozen international hit songs by the likes of Lady Gaga, Jennifer Lopez, Pitbull, Enrique Iglesias, Mika, Nicole Scherzinger, Mary J Blige, Usher, Akon, Nicki Minaj, Alexandra Burke and many others. The Moroccan-born Swede moved to the US in 2006, and currently lives in LA, where he works up his tracks in several studios, aided by Team Red, a group of additional songwriters and producers and one engineer, mixer and occasional guitarist.
The engineer, mixer and guitarist in question is called Trevor Muzzy. Since joining RedOne's team in 2009, Muzzy has worked on almost all the producer's major hits, and was nominated for a 2012 Grammy for his work on Lady Gaga's Born This Way album. This year alone, so far, RedOne has had three major 2012 US and UK hits. Muzzy engineered parts of Far East Movement's 'Live My Life', mixed Jennifer Lopez's 'Dance Again', and recorded and edited vocals for and mixed Nicki Minaj's 'Starships', as well as the other three songs RedOne co-wrote and co-produced on Minaj's recent US and UK number one album Pink Friday: Roman Reloaded.
To RedOne and his team, Muzzy's role is not so much that of a traditional mix engineer, but someone whose job is to "finish” songs. "It is semantics, really, but we use the word 'mixing' less and less, because recording engineers and producers are mixing as they go,” explains Muzzy. "The process is very different from even a few years ago, and the lines are increasingly blurred. When you're working with a great producer, you don't start from scratch when you mix one of his or her tracks. You don't want to remove the magic that's already there. A lot of mixers focus on what's bad about a track, but I feel that it's important to focus on what's good already and do my best to enhance that. I think it's the wrong approach to change it just to put your stamp on it. The main thing when you start a mix is to identify the intention of the song and the producer and the artist, and then you take it from there.
"Every song is different, of course. Sometimes finishing a song does mean tweaking it quite a bit. A good example was when I mixed 'On The Floor' [J.Lo's 2011 mega-hit], which had an amazing vibe but didn't quite have a polished mix yet, and Red wanted me to take it to the next level. That did involve a bit of deconstruction, taking it apart and putting it back together again to match the vibe while enhancing the sonics. By contrast, the 'Starship' rough mix was already very good and everybody was happy with that mix, so my job really was to maximise what was already there and to mix Nicki's vocals.”
Nicki Minaj's 'Starships' is characteristic of RedOne's production approach, marrying a Euro-dance feel and a four-to-the-floor bass drum with strong, radio-friendly melodies. As is typical of today's hits, the song was written by a large group of songwriters consisting of Minaj (Onika Maraj), RedOne, two other LA-based Swedish producers/songwriters, Carl Falk and Remi Yacoub, and well-known UK song writer Wayne Hector. Perhaps for this reason, the song is made up of several distinctly different sections. An electric-guitar intro played by Carl Falk leads into a rap verse, followed by a sung pre-chorus, the chorus itself, and a breakdown section with vocal and other effects.
Muzzy was not party to the writing, programming and arranging of the song but, once these were done, was asked by RedOne to track Nicki Minaj's vocals. "RedOne is very particular about the way he wants the vocals to sound, so he wants someone to record them who knows his approach. It's a stylistic thing, which inflections to emphasise, small details that help enhance the vocals. All Nicki's vocal tracking was done at Conway Studios in LA, where she had a lockout and was working with her engineer, Ariel Chobaz. I did not want to assume that how he was recording her wasn't working, so I asked him what he had set up, and he told me that there were two vocal signal chains, one being a Telefunken ELAM 251 going into a Chandler TG2 mic pre and then through an Urei 1176 [compressor]. The other was a more traditional Neumann-Neve chain. The 251 chain sounded amazing and worked really well with the 1176, which I don't typically use for cutting vocals. It gave her voice a unique character with a cool edge that wasn't there with the other chain. We cut Nicki's vocals in a day, and I came back and we redid a few things, so you could say it was a two-day process.
"'Starships' has a very elaborate vocal arrangement, and once everybody was happy with the vocal takes and comps, we went to the mix phase, tweaking the production mix, and finishing the song. The song has a lot of dynamics and sections, so there was a lot of potential for maximising what was there. I communicated with both Red and Nicki during the mix process. She is very involved in the process of writing and recording her songs, right up until the last step, and she's also interested in the mix process. Some artists are happy to leave all that to the producer, but she has very specific ideas about how she wants things to sound. The main mix was done here in a day, and after that I went over to Conway, where we went through things with her, and made some more minor adjustments. But with the entire session, other than the vocals, it was just a matter of adding my touch. There wasn't anything that needed rescuing. I'm working with great producers, and the songs they work on are generally already in the right direction by the time I come in to mix them.”
"The first step in starting a mix, whether I have an assistant helping me or not, is to organise the session and lay it out in a way that makes sense to me. For me. the most important thing is to group things in sections and colour-code all regions. As you can see in the 'Starships' session, I'll have the drums in red, the guitars in yellow, basses in orange, synths in blue, lead vocals in dark green and background vocals in light green. The pink track is a folder track with the sweeps and transition effects between sections. In this session, I labelled the individual vocal tracks, because the vocal sound changes throughout the songs and things come in and out. So every section has a different channel. I also combined the basses and the synths for each section. In dance music, the separation between bass and synths is increasingly a grey area. Some guys don't even look at the difference any more, as the lines have come completely blurred. But I did mark the basses in orange and synths that are more 'music' sounds in blue, because I find it helpful to separate the main low-end sounds in the track, so I can check how they work together with the kick. In dance tracks, the kick has to hit really hard, and I need to be able to quickly adjust what is happening with the bass sounds to make sure that there's room for the kick.
"In terms of how I approached the mix, when you're working with dance-orientated songs, the first thing that grabs you is the feel of the drums. So I tend to begin with the drums and maximise what's there. I generally start with the kick, and then the snare, and then I listen to how the drums sit together and how the transitions between the different sections are happening. I don't try to get the drums perfect at this stage. Once they're in the ballpark, I'll bring in the basses. As I said, the track was already pretty well mixed and together, so I fairly quickly brought in the other elements, like the guitars and the synths, and then I muted sections, treating the drums as one unit and the synths as a whole unit, and all the time thinking of the big picture. I listen to how the synths are sitting with the basses and how the basses are sitting with the drums, and so on. It's almost like working with stems. After this, I bring in the vocals.
"There are quite a few aux tracks in this session, though when you look at the vocal section in the mix window and see a 'Bus 50' mentioned among the vocal sends, it doesn't mean that I had 50 active aux tracks during the mix! Because I was working in the same session that the song was programmed in, there had been a lot of stuff in terms of bussing instruments and creating effects for them that may not have been in the session anymore. The number 50 indicates only that this many options had been used in total. Instead I probably had between 20 and 30 active auxes in the mix, which is still quite a lot. Many of those were for the vocal treatments. Logic has a function called Save Channel Strip, so when I have created some aux effects that I like a lot, I will save them, so I can pull these up in another session if I feel it will fit. The session itself added up to 142 tracks, which also seems a lot, but then many of the drum sounds, for example, were made up by layering several samples. On the other hand, all the swooshes and filter sounds for the transitions between the sections went into the pink folder [track 50] and all the 'héhé' and 'ooh' and crowd sounds in another folder , to tidy up the session.”
Drums: Logic Channel EQ, Audio Ease Altiverb
"The drums, which were all programmed, were already sitting really well in this session when I began the mix. Sometimes if the kick is lacking in punch and is swallowed up a bit too much by the bass, you have to really work to give them each their own place in the mix, typically by side-chaining the bass to the kick, and emphasising the punchy areas of the kick with EQ and/or compression. Often, when a track has only one kick sound you have to give it more of its own identity, so it has its place. But in this track that was not a problem. The kick is really punchy, it's a hard dance kick that also has a nice old-school warmth to it. It's a very organic-sounding beat for a dance record, which is a testament to the samples that were picked. Because the kick, and also the snare, were made up of several layered sounds, with one of them giving the body of the sound and another would have a clicky high end, and so on, my work was about balancing the different layers so that they sounded right in the mix, rather than applying loads of effects or EQ.
"The 'Vee claps' track is called that because it uses a sample from the Vengeance Electro sample pack. I balanced the different snare sounds in a similar way as I had balanced the kick layers. I did apply EQ to a couple of the snare layers, just to give them a little bit more identity, like on 'Extra Snare 2', I cut out all the low end and a little bit of the top end as well, so it became just this high-mid click. The rest of the drums were simply a matter of going through each of the sounds, making sure all samples sat well together, and filtering anything that I felt was in the way. All the drums are also going to an aux track with the [Audio Ease] Altiverb on it, to give them some ambience, and that was all.”
Bass: Logic Channel EQ, Waves Puigchild 670 and Maxxbass
"This track only has synth basses that have been printed as audio, with whatever effects were used during programming. The main bass in the verses is an analogue bass, like a saw bass, which gets some compression from the Waves Puigchild 670 and a little bit of Logic Channel EQ, plus some [Waves] Maxxbass on the 'Straight Bass' in the chorus. I treated each bass track individually, because they are not working together to make up a single sound, but have distinct properties. But, as with the drums, there wasn't a lot to do for me with the bass. Regarding the EQ, I don't mind using the Logic Channel EQ for some things, as it's quick and easy to use and does a pretty decent job. Otherwise, I lean heavily on Waves EQs, like the plain old Renaissance REQ6, which I use quite frequently. I also like the Waves PuigTec EQP1A, because it adds a different character, and the Softube Trident A-Range EQ has a really sweet sound for guitars in particular. I am a big fan of the Softube line. Their Tube-Tech CL1B is a killer plug-in as well.”
"You can hear in the intro that there are four guitars: two high guitars, a main one, and a low one, and then the drums kick in. The same guitar parts come in again during the second verse. The guitar sounds were good,, so I didn't do any enhancements on the individual tracks, instead sending them all to a bus  where they are treated together by a Waves Kramer PIE and C1 compressors, the Xfer LFOTool and Logic's Space Designer reverb, which was on bus 44. The PIE gave an exaggerated, pumping sound and the C1 is taking out some nastiness round 2502Hz. Rather than EQ'ing it, I tend to 'notch compress' [ie. use dynamic equalisation or frequency-selective compression], which is a Dave Pensado trick that I read about in an interview with him. The LFOtool adds some more pumping with a side-chain feel; it's a really cool plug-in. The Space Designer Nice Plate preset gives the guitars some ambience. I rely on that plug-in quite a lot. That particular setting is a really sweet, very neutral plate sound.”
"The situation with the synths in this track was similar to that with the drums and the bass: they were good as they were and the track sounded great, so I didn't do much to them in terms of treatments. The only challenge was carving out enough space for all the synths, and still leaving enough space for the drums and the vocals. I wanted to make sure that all elements had their own equal place in the mix, without killing the power of all the synths. If I have only one or two synths, I often resort to using the Waves Center or the Waves S1 Stereo Enhancer plug-ins to widen them, and use some EQ to boost and cut out some frequencies here and there. But again, as with the drums, I had many choices of synth sounds, each one very distinct, so that it mainly was a matter of balancing and panning them, and applying some general EQ, notching and boosting out some frequencies. The strings were Logic strings and I treated them as part of the synths. They appear at the point where there's a vocoder on the vocals, and the strings purely provide a nice background for that. The focus in that section is not on the strings.”
Vocals: Logic Pitch Corrector, Channel EQ and BitCrusher, Waves C1, SSL Channel, Renaissance Channel, De-Esser, Renaissance Compressor, API 2500, CLA Vocals, Doubler and VX1 Maserati Vocal Enhancer, Audio Ease Altiverb, Lexicon PCM Native Reverb
"You can see that the pre-chorus and chorus vocals have a lot of timing and comp edits. They were imported directly from the session I cut the vocals in. I did not merge or consolidate them, they just are the way they are. There's quite a lot going on with the vocals. I tried to create a nice basic vocal sound using the inserts, and once they sat well in the track, most of the sonic variations between the sections came from the sends. There was no tuning on the rapping, but the sung vocals in this track had a fair amount of tuning with the Logic Pitch Corrector plug-in on the inserts. The tuning is part of the sound of the record, with vocals needing to be very, very precise. In some cases, we pitched them up or down for vocal effects. Logic Pitch Corrector is a little harder-sounding than Auto-Tune, but it has its own distinct sound that we liked for the vocals in this track. It really fits the song.
"The other inserts on most of the vocals were all Waves: the C1 compressor, SSL Channel, Renaissance Channel, De-Esser, Renaissance Compressor, API 2500, and the Logic Channel EQ. The C1 compressor is the first in line on several lead vocals, and it does the same Pensado trick I used on the guitars, which is to compress a specific band — in the case of the verse lead vocal, around 2849Hz — focusing on notes that sounded a little harsh. It smooths this problem out more elegantly than using an EQ. Then the signal goes through the R Channel with some basic EQ, cutting significantly at 281Hz. Again, it was a matter of removing some less pleasant things to let the nice aspects shine. I bypassed the compressor in the R Channel. I needed a bit of de-essing, and the Waves De-Esser is a great all-purpose de-esser, in this case working at 5634Hz with the side-chain set to high-pass.
"There were two more compressors on her vocal. There was no science behind this, it was just a matter of experimenting to find a unique sound. The first is the Renaissance Compressor, which I love and which is set to a fast attack time and takes off about 6dB, so quite subtle, not too intense. The API 2500 is set pretty aggressively and you can hear it pumping a little bit on the vocal. It was already in the session — it had been used on the demo vocal. I pulled it over to Nicki's channel and liked what it was doing, so I adjusted it to fit her vocal. Finally, the Channel EQ notches quite a lot around 600Hz and a little bit more around 235Hz, just carving out some low-mids to make the vocal sit better in the track.
"Regarding the sends, there are some really distinct things happening here. The main lead vocal was similar throughout the song, but I tweaked it as it went along. The pre-chorus and chorus vocals all have Bus 1, which went to the same Altiverb effect that I had on the drums, to add some ambience to the vocal. The rap verses are much drier. Bus 35 is the Waves Doubler, which gives a bit of spread to the lead vocal — I used this on the rap as well as on the sung vocals. Bus 4 is the Waves CLA with a drastic telephone effect. That was another effect that was there from the demo version and added a cool quality. Bus 50 is the [Sound Toys] Echo Boy, which is the main plug-in I use for delay throws, whenever I want to repeat a word. In this case it's on a quarter-note Echoplex setting. It's a single, mono echo that I panned a little bit to the side. Bus 7 has the Waves VX1 Maserati Vocal Enhancer, and that was, again, a plug-in I inherited. It is set to a very compressed, bright vocal sound that I brought in and out to add some sparkle to the sound when necessary.
"Bus 6 has the main reverb in the track, which you are hearing in the pre-chorus and chorus, and which is a Lexicon Plate plug-in on the 'VocalPlate2' preset. It's a really bright, over-the-top plate sound that is not trying to blend in but that's actually brightening the vocal up a lot. It's loud and wet. Busses 16 and 29 are different stereo delays: the Waves SuperTap was already in the session and I kept it, and the other is a standard Logic stereo delay that I use all the time on vocals. Bus 3 is the Logic Bitcrusher, which gives the vocals a grainy sound. The vocals already had an aggressive sonic quality to them because of the 251-TG2-1176 chain, and the Bitcrusher enhanced that. It's nasty, there's nothing nice about a bit-crusher, and it adds a bit of attitude. I used it on some of the background vocals as well, like in the second verse, where you have the pitch effects. You can hear it in the very processed harmony vocals that come in. That was something we added when we were doing the final vocal comp and arrangement. It gave that second verse some more life and helped the track build. The background vocals are a very big part of the hook vocal sound as well, and, for example, track 140 has many effects on it. That actually contains the vocals of the demo singers. Nicki's lead and background vocals are dominant, but in the chorus the background vocals from Mohombi and Wayne Hector added to the crowd feeling. The chorus vocals are really big in this track, and they were part of that.”
Mix bus: Waves Puigchild & LinMB
"The session was in 24-bit/44.1kHz, and I mixed back into it, with two plug-ins on the two-bus, the Waves Puigchild compressor/limiter and the Waves LinMB multi-band compressor. Generally, I try not to be too intrusive on the two-bus, but when I took the Puigchild away, some of the life went out of the mix — it was adding something sonically unique, and was part of the sound of the track. The Puigchild has a really nice preset for mastering that's giving the two-bus a little bit of pump and excitement in the upper-mids. It helps with the overall energy. The LinMB is set almost like a dynamic EQ, doing some small last adjustments that would otherwise be done with a Waves Lin Broadband EQ. Those two plug-ins were left on for mastering, which was done by Gene Grimaldi at Oasis Mastering. He does a lot of mastering for RedOne's projects. He's respectful to what the mix is supposed to be and does an amazing job of making everything a bit louder without hurting dynamics, and bringing that last little bit of polish to the mix.” .
Trevor Muzzy's rise to the top has been remarkably quick. He took up the bass as an adolescent in the Bay Area, before attending a degree course called 'Interdisciplinary Computing In The Arts', with a focus on music, at UCSD in San Diego. (Muzzy: "It was a technical arts programme, a bachelor's degree, with a focus on anything from music theory to engineering to writing VST plug-ins.”) During his course, in 2005, he studied for five months in Sweden, but it wasn't until 2009 that he met his current employer.
"A friend introduced me to RedOne,” recalls Muzzy. "After the course, I had developed myself further through my general interest in engineering, that I've had my whole life, working on all the different DAWs, and having always been intrigued by the process of making records. I was always driven to study how it was done. My friend knew of my capabilities and I guess that Red must have recognised them, because he immediately hired me, and since then I've worked exclusively for him. Initially, I was doing a lot of vocal engineering and editing, and eventually he also gave me the opportunity to branch out into playing the guitar and mixing. Working with RedOne has given me a chance to work on a lot of exciting music, and I continue to learn from him all the time.”
Muzzy travels frequently with RedOne and says that they've been all over Europe, as well as in Morocco, and that he's now worked in every studio in LA. However, home base remains RedOne's original LA studio, which is a typical, minimalist, 21st Century, in-the-box facility, with Adam A7X monitors and a Mac running Logic. "RedOne has always been a Logic guy and is very vocal about that,” explains Muzzy. "He loves it, and everyone in his team, whether coincidence or not, likes to work with it. We all use it to keep things on the same page. My own initial attraction to Logic was to do with the power it gave me, compared to a Pro Tools LE setup. The cost of a Pro Tools systems at the time created a big barrier. You could accomplish so much more with Logic on the same computer. Of course, things have changed, but it led me to prefer working with Logic even before I met Red. Logic suits the workflow of Red's team, which involves a lot of programming but also working with many live instruments. Logic allows us to keep the process very fluid and make changes to the sessions right up until with finish the songs.”
Muzzy has mixed in several studios in Los Angeles, often using his favourite Adam A7X and Yamaha NS10 monitors, but the four RedOne songs on Minaj's most recent album were mixed in Red One's main room, as well as in Chalice Studio G in Los Angeles. "I do have an out of the box option here [at RedOne 1],” elaborates Muzzy, "which is to mix through an SSL X-Desk that I like to use just for summing purposes. Paired with the Apogee Symphony I/O, it sounds amazing. Sometimes I find that this adds some spatial and dynamic qualities that you can't quite get in the box. But it's not always appropriate or necessary, so much of the time I work in the box. This makes doing recalls and tweaks as quick as possible. Plus, nowadays the plug-ins are so good that I don't lean on outboard for the sonic aspect. I'm also really comfortable doing this with a mouse and a keyboard. There's a MIDI controller here, but I don't use it. When you're travelling a lot, it's a real advantage to be able to be so portable and not rely on specific gear for doing your work.”
