The next four years of Controlled Bleeding's output strayed from the previous trio's art rock leanings into more experimental areas. During 1983 and 1984, the band released a series of live-to-two-track cassettes via labels like Inner-X-Musick, Broken Flag, and Ladd-Frith which featured layered, harsh industrial noise, sometimes mixed with guitar and Joe Papa's vocal work. In February 1985, the band's first full-length LP, "Knees and Bones", was released by Hans Fahlberg on his Sweden-based record label Psychout Productions, featuring a particularly harsh wall of sound similar to the work of other American and Japanese harsh noise artists.
