In 1972, Stax Records hosted a concert called Wattstax (often referred to as the "Black Woodstock") for the African-American community of Los Angeles to remember the Watts Rebellion and celebrate black music and culture.

The evening will feature a discussion of Wattstax's historical context and a screening of the 103-minute documentary concert film, which is rated R. The film will be followed by a dance party featuring music from and inspired by Stax recording artists.
