Ex-Hüsker Dü/Sugar frontman BOB MOULD leaves professional-wrestling script writing, acoustic ruminations, experimental impulses and, to a large extent, dabbling in electronics behind on his new District Line release. That comes as a relief to longtime fans who not surprisingly gravitate to Mould's classic music – i.e., the late-'80s/early-'90s tougher, hook-oriented punk and power pop that remains vibrant, edgy and powerful, especially live, where his potent voice and commanding presence kick up the heat. The often dreamy, female-fronted Halou opens the Tues., MARCH 18 show. $18-$20. 8 p.m. Variety Playhouse, 1099 Euclid Ave. 404-223-1100. variety-playhouse.com.
