The Soul of Stax(1994)

"Philip Priestley's acclaimed film charts the history of Stax Records, the influential soul and blues record company founded in the 1960s by Jim Stewart and Estelle Axton. Featuring music by an impressive roster of stars, including Otis Redding, Isaac Hayes and Carla Thomas, The Soul of Stax chronicles the performers' rise through the industry and popular culture, the role played by many of them in the Civil Rights movement, and the label's eventual decline." - bfi.org.uk
