Even in their most manic moments, the Pixies have always known how to draw out a sweet, satisfying, and noisy hook. The proof can be found in their most beguiling deviations, such as in the shivering guitar of "Levitate Me" or through the spitting, snarling chaos of "The Sad Punk." But their gift for melody shines brightest on the slowed-down "UK Surf" version of "Wave of Mutilation," which reveals the song's dreamy, delicate essence.
