ZAIRE NOW DEMOCRATIC REPULIC OF CONGO

Zaïre 74 was a three day live music festival that took place on September 22 to 24, 1974 at the 20th of May Stadium in Kinshasa, Zaïre (now Democratic Republic of the Congo). The concert, conceived by South African trumpeter Hugh Masekela and record producer Stewart Levine, was meant to be a major promotional event for the heavyweight boxing championship match between Muhammad Ali and George Foreman, known as The Rumble in the Jungle. When an injury forced Foreman to postpone the fight by six weeks, the festival’s intended audience of international tourists was all but eliminated and Levine had to decide whether or not to cancel the event. The decision was made to move forward, and 80,000 people attended.
In addition to promoting the Ali-Foreman fight, the Zaire 74 event was intended to present and promote racial and cultural solidarity between African American, Afro-Latinx and African people. Thirty one performing groups, 17 from Zaire and 14 from overseas, performed. Featured performers included top R&B and soul artists from the United States such as James Brown, Bill Withers, B.B. King, and The Spinners as well as prominent African performers such as Miriam Makeba, TPOK Jazz, and Tabu Ley Rochereau. Other performers included Celia Cruz and the Fania All-Stars. source
A documentary about the Zaire 74 festival, entitled Soul Power, was released in 2009. The film was directed by Jeffrey Levy-Hinte, who served as the editor on the 1996 documentary When We Were Kings.
