In 1974, America's R&B superstars traveled to Zaire (now the Democratic Republic of the Congo) for a three-day concert. This documentary of the event, part of which became 1996's When We Were Kings, is made up of footage unseen for more than 30 years. James Brown, Bill Withers, B.B. King, the Spinners, Miriam Makeba and more perform beloved tunes, while cameras capture daily life in Kinshasa and the show's preparation.
