Chess Records was a record label named after it's owner and founder and was fondly known as "Cadillac Records" because if you stick around long enough, everyone gets one. Adrian Brody plays the record label owner who has an ear for what's up and coming, and signs Muddy Waters as his first artist. This movie is based on a true story, about the time of racial tension in the U.S., and also the time rock and roll really got its start. We meet Chuck Berry, Etta James, Little Walter, and many more original characters who helped shape the industry. Beyonce Knowles plays Etta James. Beautiful voice, beautiful actress. I love true stories - I think you can never make up anything as good. Great music in this one. Reminiscent of other music/bio pics like Ray and Walk the Line.
