Often they succeed: Mexican art-rockers Café Tacuba charge opener "La Venganza de los Pelados" with a nimble rhythmic thrust; Tom Waits adds deranged babble to "Kitate"; Rubén Blades gives "Ya Se Va" a humid open-air throb. Yet even the more conventional stuff here feels fresher than 12th albums tend to; check the submerged menace that keeps threatening to surface in "Is This All There Is?" or how off-the-cuff Mavis Staples's vocal sounds in the organ-drenched "Someday." In a long medley of Lobos' "Wicked Rain" and Bobby Womack's "Across 110th Street," the band (along with Womack) pushes past bar-band tedium into old-soul beauty. And they actually make a medley work.
