If you're a fan of American music, this provides an insight to a little-known period of the late-sixties early seventies that has now been documented for the record......finally. Although not representative of the mainstream, the list of artists from these 2 record labels does represent, in part, what Zappa wanted to offer the listening public at the time. As most commentators would label Zappa as the "King of the Freak Culture", he not only offered alternatives to so-called "new" music, but also offered alternatives to "mainstream" pop music. Before seeing this doc, I had only known of Captain Beefheart and Alice Cooper for being almost absurd responses to Psychadelic Hippie Music. After watching, I got a real sense of Zappa's vision as it pertained to his goal of giving America a view of a different musical landscape; a landscape which included people who were doing things that were not "normal" in soul music, pop music, r n b, hard rock, glam rock, doo wop, folk music and life in general. Fascinating and well made!!
