Laura Karpman and Raphael Saadiq have recently recorded their score for the upcoming dance comedy Step Sisters. The film is directed by Charles Stone (Drumline, Mr. 300) and stars Megalyn Echikunwoke, Eden Sher, Lyndon Smith, Gage Golightly, Nia Jervier, Alessandra Torresani, Marque Richardson, Naturi Naughton and Matt McGorry. The movie centers on an ambitious black sorority girl who, in order to get admitted to the law school of her dreams, agrees to cross cultural lines and teach the exclusive art of black Greek stepping to a band of wild, party-obsessed white sorority girls whose charter is about to be revoked.
