Göran Olsson’s documentary utilizes never-before-seen interviews (with Stokely Carmichael and Angela Davis among others), conducted by a group of Swedish filmmakers between the late ’60s and the mid-’70s, to chronicle the growth of the Black Power movement. Thirty years after it was shot, this lush collection of 16mm footage was found in a basement and combined with additional commentary by artists and activists who were influenced by the struggle, from Harry Belafonte to Erykah Badu. The resulting film stands as a powerful record of advocacy at a key moment in time.
