• James Brown in “Soul Power”

When the 1974 Rumble in the Jungle pitting Muhammad Ali against George Foreman was put off for Foreman to recover from a training injury, it was too late to reschedule the star-studded Zaire 74 concert, which brought together some of the era’s greatest musical performers of the African diaspora.

Jeffrey Levy-Hinte’s Soul Power, screening Thursday 10/1, captures the buildup to the concert and performances from James Brown, B.B. King, Sister Sledge, Bill Withers, The Spinners, The Crusaders, Miriam Makeba and the Fania All Stars.
