Featuring top collegiate groups from the Northeast region competing for the title of International Champions. The ICCA — that’s the International Championship of Collegiate A Cappella — takes place from January through April. It’s a bracket system, with quarterfinals, semifinals, and finals. It was founded in a college dorm room in 1996 and has since grown to include 450 groups competing in nine regions in the U.S. and Europe. Finals are in the historic Beacon Theatre in New York City.
