“Cover Versions” (** out of four) was a flashy but empty “Rashomon”-like story told from the point of view of four band members (Katie Cassidy, Drake Bell, Jerry Trainor, and Austin Swift) as they are interrogated by the police while recounting a decadent night of sex, drugs, and eventual murder before playing a music festival. Interesting in parts and loaded with style and music but like so many movies told from different points of view (“Vantage Point”, “Vanilla Sky”) it gets tiresome after a while and hard to care about.
