Procol Harum play well on this bootleg of a performance at the Fillmore West on August 3, 1970, but the limitations of its sound quality move this to the shelf reserved for fairly indiscriminate completists. It seems like this is an audience tape, and while the instruments don't come through too badly, the vocals are hollow and tinny. That makes it something that's just too difficult to play repeatedly and/or for pleasure, and only of value as rough historical evidence of how the band sounded at the time. It's too bad, as the group runs through a good assortment of material from its first four albums, though the set's by far heavier on songs from A Salty Dog and Home than the earlier pair. Also on the CD is a surprising (and also lo-fi) version of the rockabilly oldie "Move on Down the Line" that, unlike the rest of the disc, was recorded at the Fillmore West on October 30, 1970.
