Maybe the best concert you never saw

Zaire, 1974. A music festival to run alongside the Rumble in the Jungle–boxing match of the century. Dozens of greats performed: James Brown, B.B. King, Miriam Makeba, and others. A movie about the Ali-Foreman fight, When We Were Kings, took till 1996 to release from legal wrangling. A further 13-years delayed the film about the music festival, Soul Power.

It arrives in theaters next week.
