Carletta Sue Kay is the slightly unhinged gender-bending alter ego of Randy Walker, a psychotic Loretta Lynn acolyte who leads her wonky pop quartet through songs about beautiful boys and lady renegades. Named after Walker's real-life cousin (who is reportedly in jail for trying to blow up her boyfriend's house), CSK is equal parts trashy and droll: Walker's syrupy falsetto somehow manages to simultaneously channel a truck stop waitress and a gay cabaret diva.
