Despite the best efforts of EMI, Pink Floyd were still a cult band in 1969. For their fourth album, Ummagumma, they decided to hold nothing back. It's a two-LP set, containing both a live album and a new studio album. It was the complete Pink Floyd experience, for better or worse. It begins with a live rendition of Syd Barrett's "Astronomy Domine," and then moves forward through their brief career with works like "Set the Controls for the Heart of the Sun" and "A Saucerful of Secrets." Casual fans who love "Wish You Were Here" and "Money" may not find much to love here, but to the truly devoted Ummagumma is Pink Floyd at the peak of their ambitious weirdness.
