Here’s a band that can really be classified as Americana: a New Orleans quartet that relocated to Alabama after the storm and tried to capture the lost spirit of Music City, USA. It’s not quite clear where Vegas fits into the whole program; there’s certainly nothing slick or decadent about the alt.country these guys are so refreshingly adept at. It’s rustic all the way, and even if their country influences are thirdhand, these guys are nobody’s dilettantes. The title track may sound like Counting Crows covering a track from Neil Young’s Harvest, “Road Where I Was Born” may stroll down the same chord structures as the Band’s “The Weight,” and the last two tracks, “Just Another Love Song” and “Don’t Let Me Down,” qualify as the best Rolling Stones country songs in years, but there’s an inchoate sadness running through even up-tempo tracks like “Call Me, Baby,” a resigned aching for better times that the South has been wrestling with since, oh, 1865. (Make of that what you will.) When one of the dual lead singers claims “Ponchatoula just won’t be the same,” you’re not quite sure if he’s talking about permanent hurricane evacuation or romantic disappointment. But it doesn’t matter, really. That cheek-by-jowl mixture of depression and resoluteness reveals more about the region than a thousand swamp metaphors. And it makes these redfish as potentially accessible to the national audience as their blackened counterparts.
