Material is a musical group formed in 1979 and led by bass guitarist Bill Laswell. In 1978, having received a substantial royalty payment for his work with The Yardbirds, Georgian music entrepreneur Giorgio Gomelsky relocated to New York in an attempt to open up the American market to the European progressive rock/jazz-rock bands he was working with, such as Gong, Henry Cow and Magma. He established the Zu Club in Manhattan and after meeting 24 year old bass player Bill Laswell, encouraged him to form a band.
