Like a few other acts of the time (most notably The United States of America), they consciously tried to combine the contemporary sounds of rock with electronic instruments and avant-garde compositional ideas.
Interested in the ideas of experimental composers like Edgard Varèse, John Cage, Terry Riley, and George Antheil, he constructed his own custom-made electronic instrument from a combination of elements like theremins, fuzzboxes, a cardboard tube, and a speaker from a World War II bomber.
[citation needed] The record sold few copies at the time, although the group had a small but intense following in San Francisco and also toured with other acts including Blue Cheer, Chuck Berry and Fairport Convention, when the band was augmented by Robert Goldbeck (bass).
Interest in Fifty Foot Hose resurfaced in the 1990s, as they became recognized as precursors to the electronic rock sounds of groups like Pere Ubu, Chrome and Throbbing Gristle, and Cauldron was reissued on CD.
On the latter album, Fifty Foot Hose essentially comprised Marcheschi (on echolette, twin audio generators, squeaky stick, white noise generator, theremin, spark gap, and saw blades), Walter Funk III (jokers Ulysses and Cupid constructed by Fred 'Spaceman' Long, Bug (Tom Nunn), vocoder, Hologlyphic Funkaliser, and other electronix), Reid Johnston (guitube, guitar, tools, horns, harmonium, hardware, bikewheel), Lenny Bove (bass, electronics, vocals), Elizabeth Perry (vocals), and Dean Cook (drums).
