Pretty much all of the Krautrock bands when they played live, at least until 1972 or so (Can, Ash Ra Tempel, Kraftwerk, Neu!). Miles Davis in his fusion period. Flying Suacer Attack (live, at least) and E.A.R. Boredoms. The aforementioned Tim Buckley. Some of the Plastic People of the Universe's stuff. Early Grateful Dead, Quicksilver Messenger Service, Man.
