The Synthesizer. Hannah Peel, Peter Zinovieff

Tom Service investigates the rise of the synthesizer. How did this initially crude assemblage of electrical components develop in a few decades to become one of the most ubiquitous and flexible of musical instruments? He consults Peter Zinovieff, inventor of the first British commercially-available synthesizer (the VCS3, made in his garden shed in Putney); and also young composer/performer Hannah Peel, who likes to work with the sound of vintage analogue synths.
