Formed in the Motor City in 1995, the Detroit Cobras can claim they were garage back when garage wasn't cool--when, of course, it was actually coolest. And they've wavered little from their original formula, building a catalog that's mostly covers of 50s and 60s R & B, rock, and girl-group obscurities. Rachel Nagy's husky, molasses-thick voice pools around the bone-simple tracks, and the band's two guitarists are more enamored with the shapes of a few clear notes than with razzle-dazzle runs. On their third full-length, Baby, released overseas on Rough Trade in November (they're currently shopping for a new U.S. label), a wistful mood, ham-fisted double entendres, and the occasional stroke of dark winsome genius combine to paint a picture of soulful innocence, despite all evidence that they lost it long ago.
