Garbage have spent four years finding their way back to the grungy guitars, girl-group melodies and adolescent angst that made them famous. But Shirley Manson and her misunderstood-bad-girl persona remain unscathed. Falling somewhere between boy-baiting Madonna and the Boy's-Own style of Chrissie Hynde, she entices and discards with equal disdain. "I'm no Barbie doll, I'm not your baby girl," she sings in Why Do You Love Me, like a bra-burning Ronnie Spector. Boys Wanna Fight equates world politics with a Saturday night punch-up - which might be merely a simplification. She is equally voyeuristic on Bleed Like Me, coldly observing self-imposed starvation, self-harming and sexual confusion.
