The king of shock rock, Alice Cooper, returns to Chastain Park Amphitheatre AUG. 26, unearthing a set of gory and theatrical monster-rock cuts. With his undead exterior and born-again facade, Cooper remains a legend, albeit not very scary anymore. Arena-rock hoodwinks Cheap Trick open the show, churning out a haze of power-pop anthems that remain just as catchy as they were three decades ago. $27.84-$72.12. 7:30 p.m. 4469 Stella Drive. 404-733-5000. http://www.classicchastain.org/">www.classicchastain.org;.
