The most incredible salsa band from New York City : the Fania All Stars (Celia Cruz, Ray Barretto, Hector lavoe, Larry Harlow…). The band was invited among many others afro-americans stars (Buddy Guy, James Brown..) in 7974 for the Ali / Foreman fight organised in Zaïre by Mobutu. This whole cult document is filmed by Leon Gast, director of When We Were Kings.
