Material

American experimental punk-jazz-funk-noise-electro band, founded circa 1978/79 by bassist [a=Bill Laswell] and keyboard player [a=Michael Beinhorn].
Material was not only a band name, but an alias for the intensive production work of the duo (for [a=Afrika Bambaataa], [a=Herbie Hancock], [a=Nona Hendryx] ...).

[a=Michael Beinhorn] left the 'band' in 1985. In the 90s, Material became more world/indian/afro/ambient/dub-oriented.
