Laurence Cottle is an electric bass guitarist and composer. His solo recordings have been mostly in the jazz and jazz-fusion vein, with such notable releases as Five Seasons, Laurence Cottle Quintet Live and others. He was a member of the Los Angeles, California-based fusion quartet, The Fents, and appears on their second album, The Other Side, released on the Passport Jazz label in 1987. Shortly after, he was hired by British heavy metal band Black Sabbath to play bass on the studio sessions that would become their 1988 album Headless Cross. Cottle wrote and played all the bass parts for the album, but did perform live or tour with the band. Cottle produced three albums for guitarist Jim Mullen in the 1990s, recorded with British jazz musicians Mornington Lockett, Tim Garland, Django Bates, Gerard Presencer and John Graham. He has written music for film and television including the television programs Friends and The Oprah Winfrey Show.[clarification needed] Cottle was a member of Bill Bruford's Earthworks from 2003 to 2006.
