He first attracted wide attention in the late 80s, playing electric bass with John Scofield on tour and on several recording sessions, including two late 80s Gramavision albums, Blue Matter and Loud Jazz. After leaving Scofield he teamed up with the band’s drummer, Dennis Chambers, forming the funk band, Graffiti. He has also recorded with Carl Filipiak and Haakon Graf.
