Caitlin Rose has one of the most intriguing voices in music. She never sounds like she’s bearing down too hard on any of the 12 songs on her just-released sophomore album “The Stand-In” (ATO Records); and yet her voice can just eviscerate the non-wary, perfectly crystalizing a range of wistful emotions within luscious twang-pop arrangements. She’ll show off the album Thursday at Chapel Hill’s Local 506. Showtime is 9 p.m., cover is $10 and Andrew Combs and Michael Rank are also on the bill. See local506.com for details.
