Cadillac Records stars Beyonce, Mof Def, Jeffrey Wright and Adrien Brody with the soundtrack featuring Beyonce, Mof Def, Columbus Short, Mary Mary, Raphael Saadiq, Solange, Little Walter and Nas with Olu Dara. The movie is about Leonard Chess who co-founded Chess Records, the pre-eminent blues label of the Fifties and Sixties, with his brother Phil. They formed Aristocrat Records in 1947 and the Chess label two years later with a mind-boggling flood of Blues, R&B plus Rock"N"Roll talent- Muddy Waters, Howlin" Wolf, Bo Diddley, Chuck Berry, Willie Dixon, Etta James and Little Walter. Phil focused on jazz while Leonard Chess honed in on roots music, making Chess the greatest repository of Black music at mid-century.
