A cappella has been around for a long time but has seen a resurgence in popularity with movies like “Pitch Perfect” and musical group Pentatonix. Acappellooza will be sure to excite fans of a cappella. A friendly competition of prizes and celebrity judges will satiate those who remember when Glee was still on the air — and actually good. With the top five a cappella groups in the Denver area, Acappelloza will showcase the Sound of the Rockies’ preview of their set that they will perform at the International Barbershop Chorus Contest.
7:30 P.M., June 22. Tickets range from $24-$32. Newman Center for the Performing Arts, 2344 E. Iliff Ave. soundoftherockies.com. tinyurl.com/y5qex6wm; 303-871-7720.
