Long before Ry Cooder, Leo Kottke, Richard Thompson, and others were impressing listeners with their ability to hop from genre to genre, Sandy Bull glided from classical and jazz to ethnic music and rock & roll with grace and verve. Accompanied on his first two albums by renowned jazz drummer Billy Higgins, Bull produced some of the first extended instrumental compositions for guitar that incorporated elements of folk, jazz, and Indian and Arabic-influenced dronish modes. Not "rock" by any stretch of the imagination, it's nevertheless easy to see that it could have had an influence on the rock musicians who began incorporating eclectic and Middle Eastern sensibilities into their music a few years later. After his debut, Bull expanded his arsenal from the acoustic guitar and banjo to include oud, bass, and electric guitar. After his second album, however, his recordings were less focused and less impressive. In the 1970s, he dropped out of music altogether due to drug problems, although he began recording again in the late '80s. On April 11, 2001, Sandy Bull died of lung cancer at his home just outside of Nashville.
