SOS Art 2012, the most powerful local statement for two vital but elusive goals — peace and justice — begins a 10-day run at the Art Academy Friday evening. More than 200 artists — visual, literary, musical and performers of all ages — are taking part in this 10th appearance of founder Saad Ghosn’s visionary gathering of works promoting these important ends. Friday’s opening starts at 6 p.m., and at 7 p.m. art historian Jay Zumeta will give an introductory talk to be followed by a gallery walk with brief talks by participating artists. At 9 p.m. a potluck reception begins with music by the Lastboppers. No charge for the special events, scheduled Friday, Saturday and Sunday evenings of both weekends, or for the exhibition itself, open to the public during Academy hours: 9 a.m.-6 p.m. Monday-Thursday; 9 a.m.-midnight Friday and Saturday; noon-6 p.m. Sunday. Through June 10. Art Academy, 1212 Jackson St., Over-the-Rhine.
