Presenter: Paul White - Biog

Paul White initially trained in electronics at the Royal Radar Establishment in Malvern then went on to work with Malvern Instruments, a company specialising in laser analysis equipment, before moving into technical writing.

He joined the Sound On Sound team in 1991 where he became Editor In Chief, a position he held for many years before becoming Executive Editor in 2020. Paul has written more than 20 recording and music technology textbooks, the latest being The Producer’s Manual.

Having established his own multitrack home studio in the 1980s Paul has worked with many notable names, including guitarists Bert Jansch and Gordon Giltrap.

He’s played in various bands over the years and currently collaborates with Malvern musician Mark Soden, under the name of Cydonia Collective.

Paul still performs live claiming that he has suffered for his music so he doesn’t see why everyone else shouldn’t too!
