“The Black Power Mixtape 1967-1975” mobilizes a treasure trove of 16mm material shot by Swedish journalists who came to the US drawn by stories of urban unrest and revolution. Gaining access to many of the leaders of the Black Power Movement — Stokely Carmichael, Bobby Seale, Angela Davis and Eldridge Cleaver among them — the filmmakers captured them in intimate moments and remarkably unguarded interviews. Thirty years later, this lush collection was found languishing in the basement of Swedish Television. Director Göran Olsson and co-producer Danny Glover bring this footage to light in a mosaic of images, music and narration chronicling the evolution one of our nation’s most indelible turning points, the Black Power movement.
