Fifty Foot Hose were one of the most unusual '60s San Francisco psychedelic bands, in part because they weren't really that psychedelic. Like a few other acts of the time (most notably the United States of America), they were trying to fuse the contemporary sounds of rock with electronic instruments and avant-garde compositional ideas. Only one album resulted from the ambitious enterprise, and that record (Cauldron, 1968) still remains unknown to all but hardcore collectors. Although an erratic work, it was intriguing for its mix of jazzy psychedelic rock tunes with electronic sound effects that anticipated future models of synthesizers, but sounded fiercer and more primitive.
