Richard Lowe Teitelbaum (May 19, 1939 - April 9, 2020) was an avant-garde composer, synthesizer keyboardist, and improvisor. He was a pioneer in live electronic music, brain-wave controlled synthesizer music, and brought many different world music performers together.
Richard was a professor of electronic music at Bard College for over 30 years and he was the first person to take a Moog synthesizer on tour in Europe with his group Musica Elettronica Viva (MEV) with Alvin Curran and Frederic Rzewski.
