Cauldron was Fifty Foot Hose"s first and most famous recorded work, released on Limelight Records in 1968. Founded by Cork Marcheschi, the band played continuously around the Bay area of northern California throughout the mid-"60s. Marcheschi, who had developed a taste for R&B and the avant-garde music of composers such as Edgard VarŠse, started out as the band"s bass player, but his interest in experimental music prompted him to develop his own musical instrument, similar in function to the hybrid developed by Simeon Cox, and which was the underpinning of the Silver Apples" sound. The band played a lot of gigs, but the experimental nature of their music tended to perplex audiences unused to such sounds.
