Ultimately, it takes Dave Grohl to help propel her out of her shell--or to at least come close. Grohl and Foo Fighters bandmate Taylor Hawkins slap a double-drum arrangement on "He War," so that when Cat Power sings "I'm not that hot chick/And if you want me to run with it/We're onto your same old trick" in vocals that sound filtered through a phonograph, it actually takes on the intended urgency. You Are Free is definitive work from an artist who--outwardly anyway--doesn't want to be definitive about anything, which perhaps makes Marshall the rock-and-roll equivalent of the ugly duckling. Cat Power is truly a swan, but will she ever realize it?
