Though Zoe Muth’s debut album is nothing less than superb, even unabashed superfans like me must admit that the songs themselves are quite simple. But as songwriters like Woody Guthrie and Hank Williams once proved, it’s not technical complexity that makes a country song great: it’s the feeling with which it is performed. And feeling is something Zoe Muth’s always had in spades. But after hearing her perform a few new songs at the Blue Moon two weeks ago, it’s become clear that Ms. Muth’s songs are maturing. She’s begun to employ more complex song structures (thanks in no small part to her excellent band the Lost High Rollers), but without sacrificing any of the classic country timelessness that makes her songs so compelling. This girl has really got something; I’ll be downright shocked if Bloodshot Records and New West haven’t started a bidding war over her before the year’s out. All ages. Free. SARA BRICKNER
