Emory University’s ChaiTunes competes with eight other teams in Hillel’s eighth annual Kol HaOlam, the collegiate Jewish a cappella national championships, on Saturday night, March 10, at Adas Israel Congregation in Washington. Although a team from New York University won the competition and was the audience favorite, Emory’s Joshua Perlin was named the best beatboxer. Other ChaiTunes members are Xiaochen Chen, Sahrudh Dharanendra, Julia Dorfman, Sara Frank, Tulasi Kadiyala, David Kulp, Julia Lawrence, Briley Newell, Dom Refuerzo, Jessica Soforenka, Colleen Su and Mark Wang.
