Negativland
Since 1980, the 4 or 5 or 6 (or more) Floptops known as Negativland, a multimedia collective originally from the San Francisco Bay Area, have been creating records, CDs, video, fine art, books, radio and live performance using appropriated sounds, images, objects, and text. Mixing original materials and original music with things taken from corporately owned mass culture and the world around them, Negativland surreally re-arrange these found bits and pieces to make them say and suggest things that they never intended to.
