Merrill Garbus's teemingly inventive debut led to much name-dropping in indie circles, while the tribal beats of her second album established her at the wilder frontiers of US pop. There's no shortage of ideas on her third; its pile-up of playground chants, synth squelches and percussive clutter delivers some terrific moments but the songs' fidgety unpredictability comes at a price. Garbus's voice is jostled too much amid the hectic production to allow its personality to shine through and, with some notable exceptions (the call and response of Real Thing), hooks are hurried on before properly taking root.
