Just when you thought you'd seen every holiday-themed show done to death, Theatrical Outfit and Georgia State University turn up an overlooked gem. Professors, alumni and students at GSU's School of Music perform AMAHL AND THE NIGHT VISITORS, a short opera by Gian Carlo Menotti about a disabled child, his impoverished mother and the unexpected gift of the Magi. As an English-language opera than runs just under an hour, it's a great gateway for young people who don't know the form. Through Dec. 23. $15-$25. Tues., Thurs.-Sat., 7:30 p.m.; Sun., 2:30 p.m.; Dec. 19, Dec. 23, 2:30 p.m. Balzer Theater at Herren's, 84 Luckie St. 678-528-1500. www.theatricaloutfit.org.
