Alcatraz

 ong-running, but obscure, Krautrock band. Alcatraz went through many genres, starting as jazzy-edged prog with psychedelic touches. Their debut LP was famously recorded at Faust's Wümme Studio. After that albums were sporadic, and line-up changes frequent, first moving into polit-rock akin to Floh De Cologne, then into jazz-fusion.
