Sandy Bull, June 18, 1976, Paramount Theater, Oakland, 22-16-23. Sandy Bull was a composer and accomplished player of many stringed instruments, including guitar, pedal-steel, banjo and oud. His music and recordings are characterized by his blending of non-western instrumentation and improvisational traditions with the 1960s folk revival. His albums for Vanguard Records often combined extended modal improvisations on oud with an eclectic repertoire of instrumental cover material. His approach to performance, composition and recording is notable for his extensive use of overdubbing and multi-track tape recording before such techniques became commonplace in music production.
