Allen Hightower will direct as they perform at the 2021 national conference of the American Choral Directors Association (ACDA). Only 24 choirs from across the United States have been invited. A Cappella is one of only three university mixed choirs invited nationally and the only mixed university/college choir from Texas. This is the fourth appearance of the UNT A Cappella choir at the national conference in 22 years conducted under Mel Ivey, Jerry McCoy and, now, Allen Hightower. The conference will be held in Dallas in March 2021.
