“Brundibar,” a musical work set in a concentration camp, was performed last weekend through a collaboration of local arts groups. Baritone Lawrence Indik, an associate professor of voice at Temple's Boyer College of Music and Dance, who played the role of Brundibar, said that most of his grandfather's family was killed during World War II. Performing in "Brundibar" has personal meaning for him. "It's a beautiful work, and there's so much meaning to it."
