Love this video!
From a comment on YouTube:
“… it’s a clip from “Wattstax”, a 1973 documentary film by Mel Stuart that focused on the 1972 Wattstax music festival
The concert was held at the Los Angeles Coliseum on August 20, 1972, and organized by Memphis’s Stax Records to commemorate the seventh anniversary of the Watts riots. Wattstax was seen by some as “the Afro-American answer to Woodstock”. To enable as many members of the black community in L.A. to attend as possible, tickets were sold for only $1.00 each.”
