It's refreshing to hear a pretty girl from Texas singing REAL COUNTRY MUSIC again. I know, Miranda Lambert's hot and all, but she is part of the Nashville machinery. SUNNY SWEENEY is doing her thing the way she wants to Tues., MAY 20, and the gal can wail like Loretta when she wants to. $7. 8 p.m. Smith's Olde Bar, 1578 Piedmont Ave. 404-875-1522. www.smithsoldebar.com.
