Doug McKechnie (b. 1941) is one of the last people alive who attended the VORTEX concerts (1957-59) and he later revived a version of VORTEX in 1973 with Belson’s permission and consultation. A pioneer of the Moog synthesizer, he performed on the Grateful Dead album Aoxomoxoa (1969) and appeared live with the band. Also in 1969 McKechnie used the Moog synthesizer for a performance of Terry Riley’s In C at the San Francisco Opera House. Other performances included The Family Dog concert hall, the opening of Frank Oppenheimer’s Exploratorium, and the first ever concert at the Berkeley Art Museum. McKechnie will lecture, screen films, and perform live soundtracks.
