Charles Cohen is a Philadelphia, Pennsylvania area-based free jazz musician and composer. Creating music since 1971, his music is entirely improvisational and produced solely on a vintage Buchla Music Easel synthesizer, an extremely rare integrated analog performance instrument made by synthesizer pioneer Don Buchla. He has been increasingly recognized for his artistry performing internationally and is one of a handful of musicians who has mastered the Buchla Music Easel, an extremely rare instrument. Only twenty-five of the instruments were produced in the early 1970s and only a few have survived. He is also considered a pioneer in synthesizers and performance music.
He says he was inspired by free jazz pianist Cecil Taylor. Cohen worked for many years with musician Jeff Cain in their group The Ghostwriters. He works with other media artists in improvisational settings such as the Red Room, Knitting Factory and Tonic. Cohen concentrates on creating electronic music in the setting of the live performance space. He is openly gay and has performed in LGBT-specific performances, events and venues.
