At first, you'll think you're hearing early Foreigner, but within seconds a sleek, new kind of rock-soul pattern emerges. On top of this, Auerbach, an incredibly unpretentious and modest singer, alternates between an evil drawl and a full-on blues howl.

As bass pumps high octane, the guitarist whips out a bravura stroke, a dazzling lead break that is extraordinary more for all the notes that are left out than the ones that are actually featured. Make no mistake, though, we are witnessing the emergence of a true guitar hero in the form on Dan Auerbach.

The tempo slows down as the song, and the album, cools. The Keys have burned up all they've got at this point; their fervor has been intelligently and imaginatively rendered. Clock this 38-minute slice of wonder as one of 2011's most entertaining, daring and important works - one with handclaps to spare.
