The Gallery at East Atlanta Tattoo is riding high on its wave of lowbrow art events that have grown in attendance since the gallery's inception in September. June's Monster Mayhem, a phantasmagoric celebration of '50s- and '60s-inspired monster and sci-fi iconography, packed in nearly 600 fans. Next comes 4 ON THE FLOOR Sat., JULY 19, with up-and-comers Jessica Elaine Blinkhorn, Dave MacDowell, Emma Mount and Brandi Read. Their anything-goes approach references popular culture without feeling stale, with vivid colors and a surprising dose of narrative. Through Aug. 2. Free. Reception, 7-11 p.m.; Thurs.-Sat., 5-8 p.m., or by appointment. 1188-B Glenwood Ave. 404-226-2279. www.lowbrowgalleryatlanta.com.
