Controlled Bleeding was a prolific experimental music group based in Massapequa, New York. The group was founded by Paul Lemos, the group’s only consistent member. Most of Controlled Bleeding’s released recordings feature two main collaborators, Chris Moriarty and vocalist Joe Papa, who both died in the late 2000s.

Due to the broad musical interests of the main collaborators, as well as the influence of the band’s relationships with genre-focused labels like Wax Trax! and Roadrunner, Controlled Bleeding’s total recorded output spans many different genres including harsh noise, dub, progressive rock, industrial dance, metal, gothic, darkwave, classical, sacred music, ambient, free jazz improvisation, and musique concrète. Through the 80s and 90s, they would often release two or more full-length albums of music in the same year featuring radically different musical styles.
