Roger Dumas was a synthesizer whiz kid back in the 70s. He wrote manuals for early Moog synthesizers, and he helped out Prince, Janet Jackson, and even John Lennon. He’s also the guy behind the catchy synths in the disco hit “Funkytown.” Now Roger has a new passion: studying the brain’s response to music. He’s done some pretty amazing work, including re-creating a melody out of the pure data from brain sensors. In this season premiere episode of Composer Quest, I talk with Roger about his research, his album based entirely on brain data, and his glory days in the music business.
