“I’m a feminist/And if that offends you, then fuck you!” barks Kate Nash over rackety garagerock guitars. Nash’s 2007 debut topped the U.K. charts, but on her third LP she’s moved a long way from her old twee piano-backed confessions. Or has she? The album is self-released (Nash raised money for the record on the website PledgeMusic); the sound is “indie” (she’s been listening to Best Coast); the lyrics are pugnaciously “political” (lots of half-digested gender theory). But Nash can’t sing or rap – she tries to do both – and her tunes are anemic; her punk postures are borrowed from musicians smarter and more talented than she. Nash sings, “I’m a freaky, freaky, freaky, freaky girl.” No, you’re not.
