This is a bootleg album, released by Frank Zappa without enhancement, and also available as part of the Beat The Boots! #2 boxed set. It's a two-CD set that presents a nearly complete live performance by the 1970-71 "Flo & Eddie" edition of The Mothers, featuring lead vocalists Howard Kaylan and Mark Volman, and recorded December 4, 1971. As such, it begins with an extended instrumental introduction leading into "Peaches En Regalia," and then there is a combination of 200 Motels material and oldies like "Call Any Vegetable." Sound quality is good, and the performance level is high.
Hence, the critical verdict is: good, for a bootleg. Of course, this recording also has historical value, apart from its musical attributes. The show, which occurred at the Casino in Montreux, Switzerland, ended in a fire that destroyed The Mothers' equipment. The following week in London, Zappa was pushed off the stage by a deranged fan, and this edition of The Mothers was history.
