Seven a cappella groups performed in GW Class Council’s Battle of the A Cappellas. The GW Vibes took first place this year, beating last year’s winner, the Sons of Pitch.

Each group performed two songs and were judged by an administrator, a student and a guest judge from the national organization Chorus America.

This post has been updated to reflect the following correction: 

The Hatchet incorrectly identified the GW MotherFunkers as the winner of last year’s Battle of the A Cappellas. Sons of Pitch had won the event. We regret this error.
