Great group, but while they did have SOME influence on these genres, I think that is, in part, exaggerated and/ or revisionist history. They belong to the late 60's/ early 70's, and the strongly political/ social context of their music has relatively little to do with the topical concerns of punk/ postpunk rock, although I guess that their high energy rock and anti-authoritarian attitude was indeed a forerunner of sorts. They really had little in common , musically, with most of the acts on this list, as they were influenced at times by free jazz and the Stones, and some of their material is hard pop or proto-metal.
