Come see competitive high school a cappella groups perform in the Stinger A Cappella Invitational Exhibition Competition. Groups will perform by ICHSA guidelines and be judged using the competition rubric, but the event is primarily an opportunity for groups to perform their competitive set for feedback before the start of the competitive season. If you love Pitch Perfect, then this is the concert to come to see! Come support our singers!  

All proceeds benefit the Hinsdale South Music Boosters and Music Department.
