A genre and generation-spanning assortment of artists have contributed to an album of music dedicated to and inspired by the Occupy movement. "Occupy this Album" features 99 "fan favorites" and unreleased tracks by Willie Nelson, Dave Crosby and Graham Nash, Ani DiFranco, former Dresden Dolls singer Amanda Palmer, Yoko Ono and more, and will be out May 15.

The album will be available as 4 CDs and in digital download formats. It was produced by Music for Occupy, a nonprofit production company dedicated to and affiliated with the Occupy movement. The company's website describes its mission as a re-invention of protest music, to "produce music and events relevant to our times" while retaining an independent artistic vision and dedicating a portion of all profits to directly sustaining the Occupy movement.

Distribution and promotion of "Occupy this Album" will be handled by the New York City independent label Razor and Tie. A record release party is planned for May 8 at New York's City Winery, featuring performances by DJ Logic, George Martinez and the Global Block Collective, and filmmaker Michael Moore.
