I want to know the answer to the following question:
What popular a capella competition is not specific to college groups?
All the background I'm provided with is that "Increased interest in modern a cappella (particularly collegiate a cappella) can be seen in the growth of awards such as the Contemporary A Cappella Recording Awards (overseen by the Contemporary A Cappella Society) and competitions such as the International Championship of Collegiate A Cappella for college groups and the Harmony Sweepstakes for all groups.". Is that enough to answer the question?
