New Orleans' finest purveyors of drum-free classic country are back with pluck and twang to spare. The four-piece string band combines obscure classics with anachronistically perfect originals like the Cajun-inflcted sobber "Lonely Mardi Gras," driven by bandleader and formerly local New Orleans music historian Mike Hurtt's signature rasp, which sounds like it was dug up out of a time capsule planted at a Delta crossroads. Here, they'll trade tunes with Louisiana rockabilly great Jay Chevalier, whose legacy includes topical gems like "The Ballad of Earl K. Long," "Castro Rock" and, most recently, "The Ballad of Harry Lee." The Hearts recently dropped their first full-length album, Come Back to Louisiana (self-released). Particularly if you missed Chevalier and the Haunted Hearts at this year's Ponderosa Stomp roots-music festival in Memphis, this is a date to catch -- the Hearts now live in three different states. Free admission. -- FENSTERSTOCK 8 p.m. Sat., May 20
