Constructed from footage and interviews done by Swedish filmmakers in the late 60s and early 70s, Black Power Mixtapes shows never-before seen sides of major players in the movement.  Our Movie Moles Denise Morris and Laurie Mercier discuss what it tells us.  The film is showing through Thursday, 11/3 at Cinema 21.   A documentary on the period can be seen here, and more about the Swedish film here.
