Producers say "Occupy This Album" will "provide an anthem and rallying cry for the protestors involved" in the uprising.
Among the artists lending their music and their support to the album: Third Eye Blind, Devo, David Crosby, Graham Nash, Jackson Browne and documentary filmmaker Michael Moore.
The album is due out this winter.
All proceeds will go to the Occupy movement, with the Los Angeles movement getting some of that money.
