DVD: Cadillac Records, (Sony)

Adrien Brody stars as the co-founder of Cadillac Records, the Chicago label that signed Muddy Waters (Jeffrey Wright), Howlin’ Wolf (Eamonn Walker), Chuck Berry (Mos Def) and Etta James (Beyoncé Knowles). It’s a legendary line-up, but Cadillac Records doesn’t delve any deeper into the musicians’ psyches than the liner notes of a Best of Chess CD. Each artist gets a brief moment in the spotlight, before they’re brought down by sex, drugs and/or alcohol, and the film moves on.
