Welcome to the Intergalactic Community of A Cappella (IGCAC) website!

The IGCAC is the organization that oversees all things a cappella at Brown University. There are currently 11 groups under the IGCAC, each group with their distinct style. Brown is proud to have the most a cappella groups per capita in the US and home to International Championships of Collegiate A Cappella award-winning groups the Higher Keys, the Jabberwocks, and the Brown Derbies. Many of our groups have also been featured in Best of Collegiate A Cappella (BOCA) and Voices Only albums, including the Brown Derbies, the Chattertocks, the Jabberwocks, the Higher Keys, and the Ursa Minors.

Our audition schedules and locations as well as a cappella events calendar can be found on this website. Please use this website as your homepage for all things a cappella!
