Alexander Bull (February 25, 1941 – April 11, 2001) was an American folk musician and composer. Bull was an accomplished player of many stringed instruments, including guitar, pedal steel guitar, banjo, and oud. His early work blends non-western instruments with 1960s folk revival, and has been cited as important in the development of psychedelic music.
His albums often presented an eclectic repertoire including extended modal improvisations on oud. An arrangement of Carl Orff's composition Carmina Burana for 5-string banjo appears on his first album and other musical fusions include his adaptation of Luiz Bonfá's "Manhã de Carnaval", a lengthy variation on "Memphis Tennessee" by Chuck Berry, and compositions derived from works of J. S. Bach and Roebuck Staples.
Bull used overdubbing as a way to accompany himself. As ed in the Still Valentine's Day, 1969: Live At the Matrix, San Francisco recording, Sandy Bull's use of tape accompaniment was part of his solo performances in concert as well.
Bull primarily played a finger-picking style of guitar and banjo and his style has been compared to that of John Fahey and Robbie Basho of the early Takoma label in the 1960s. Guitarist Guthrie Thomas credits Bull as being a major influence in his early playing career.
