ERIC SARDINAS looks like a metalhead, but his roots lie deep in the Mississippi Delta. With a tendency to overdo it at times, he isn't exactly a by-the-book blues re-enactor, but the man's picking is smokin' hot. Charlie Sheets opens. $12. 8 p.m. Smith's Olde Bar, 1578 Piedmont Ave. 404-875-1522. www.smithsoldebar.com.
