The SXSW gravy train is about dried up. But before it’s all sopped, here come Limbeck, from the real O.C. They play sunny, hook-heavy pop-rock that sounds like it could easily be the soundtrack to a spring night of drinking. From the other side of things, Greensboro’s House of Fools sound like a band that should be touring with Limbeck. Shuffling rock, with bababas and nice harmonies. And John Ralston, who has a Belle and Sebastian jones. At White Water, 8 p.m., $5.
