Smegma is an avant-garde experimental music collective that emerged from Los Angeles in the 1970s, known for their innovative approach to instrumental composition and unconventional sound design. The group has maintained a deliberately obscure public presence throughout their decades-long career, releasing music primarily through limited editions and underground channels while building a devoted cult following. Their work spans from tape loops and electronic experimentation to free improvisation, establishing them as influential pioneers in the experimental and noise music scenes.
