Zoë Blade - Biog

As a teenager, Zoë Blade sampled household objects into Impulse Tracker, twisting them into rhythmic alien soundscapes.  Not quite music, but not quite not, the result was a bizarre example of outsider art.

She's since honed her aesthetic into something more polished but no less unique, fusing catchy melodies and rhythms with the untamed sound of her sprawling modular synthesizers.

She's currently making music for popular YouTube series ContraPoints, as well as her patrons at and is also involved with Nina in the Transistor Sounds Labs company.

Nina Richards - Biog

Nina Richards is the kind of musician who always likes to dive a level deeper.  Always looking to improve the tools available, she designed and built Stepper Acid, a modular sequencer loosely based on the TB-303, but geared more towards live performance.

This was well received by other musicians too, and has been used by the likes of Nine Inch Nails's Trent Reznor and Underworld's Rick Smith. The product is marketed through her Transistor Sounds Labs company.

In addition to her solo work, Nina is also known for writing music for actress Abigail Thorn's YouTube channel Philosophy Tube.
