Break out your old bridesmaid dresses, wedding gowns and tuxedos for the world premiere of THE MARRIAGE PROJECT, a multimedia art piece by Atlanta's Beacon Dance. Inspired by the past, present and future of matrimony, the public art performance strives for a more thoughtful dialogue around the subject of marriage in contemporary American culture. Audience members are encouraged to blend in with the players, who include dancers, actors, musicians, visual artists and poets, at First Existentialist Congregation of Atlanta. A wedding-themed reception follows the performance. Reservations are encouraged. Free. Fri.-Sat., 8:30 p.m.; Sun., 5:30 p.m. 470 Candler Park Drive. 404-377-2929. www.beacondance.org.
