Experimental noise band, formed in Boston 1978. Notorious for their early recordings which were exercises in brutal noise, such as their infamous 1985 album Knees and Bones which utilised pneumatic drills, metal percussion and cement mixers as sound sources. Subsequent albums delved into sonic and textural experimentation as the band gradually grew more sophisticated and palatable, however a number of less experimental, commercial industrial albums were released on Wax Trax! in the late 1980s. Nontheless, Controlled Bleeding’s sound varies from album to album and at one time or another has contained elements of dub, free jazz, noise, prog rock, sacred music, dark ambient, classical and musique concrète.
