Kim Gordon has had a rough few years. Her marriage disintegrated at the same time as Sonic Youth, the band she and philandering ex-husband Thurston Moore shared for three decades. With Body/Head, the noisy duo the 60-year-old recently formed with guitarist Bill Nace, Gordon shows off her signature, muscular vocal quaver, amid plenty of thunderous Sonic Youth-style feedback and guitar creep. Titles aren’t exactly subtle (“Murderess,” “Last Mistress”), even if the twin-guitar jams are opaque. And when she sings, “I can only/Think of you/In the abstract,” we swear we have absolutely no idea whom she is referring to.
