“Old Reliable” might sound a bit like a diss, but when it comes to the Drive-By Truckers, that label can be applied with a smile and shake of the head—after over a decade, the band is still churning out songs like “This Fucking Job,” a track that manages to be both socio-politically relevant and a rampaging, propulsive rock gem, and “Santa Fe,” a ballad so lilting and dreamy that it’s easy to miss how darn sad it is. Reliable, yes, but also remarkable. Both those songs appear on The Big To-Do, the band’s eighth studio full-length and their first on ATO. On the heals of the sprawling, melancholy Brighter Than Creation’s Dark, To-Do feels concise — a taut bundle of hooks and spot-on observations. Anyone who’s ever spent time on a local rock scene will be charmed and saddened by Patterson Hood’s “After the Scene Dies,” while Mike Cooley’s “Get Downtown” captures recession-era anxiety with humor and honky-tonk snarl.
