They've already got a summer jazz series; now they're doing gospel as well. It's all happening at Villa Christina, 4000 Summit Blvd., Atlanta. Beginning Sunday, the lawns and gardens behind the restaurant will be rocking to old-time gospel and jazz. Upcoming dates include July 13 and Aug. 24. As with all the Villa music events, admission is free but no coolers or picnic baskets are allowed; you may bring in blankets and lawn chairs. The doors open at 4 p.m. and the music kicks off at 5:30 p.m. Details are online at www.villachristina.com; 404-303-0133.
