Negativland is an experimental music and art collective founded in 1979 in the San Francisco Bay Area, known for their innovative use of sampling, sound collage, and media deconstruction. The group has challenged conventional notions of authorship and copyright through provocative albums and performances that blend found sounds, spoken word, and abstract compositions. Their influential work spans decades of cultural commentary and avant-garde soundscapes that continue to inspire artists and audiences interested in experimental and conceptual music.
