DIRT BAG LOVE AFFAIR — This Charlotte quartet gets down and dirty, as the name implies. They offer a fine line between rock and punk in a style that offers a bit of nostalgia for the hair metal of old. There's plenty of songs about drinking here, so raise one up and toast the type of rock where punk is celebrated as much as passing out. Opening for L.A. Guns with Shadow of Myself. (Jeff Hahne)
