The Deaftones is a co-ed collegiate a cappella group from Rider University, located in Lawrenceville, NJ. The group is currently comprised of eighteen students from Westminster Choir College, the music school of Rider University, as well as Rider University as a whole. The group was created in 2007 by Patrick Dillon, on Westminster's campus. Since then, it has grown into a well-known competing a cappella group. The Deaftones now perform in the ICCA's, the International Championship for Collegiate A Cappella. They look forward to another year of performance and competition with some of the best a cappella groups in the world.

The group performs a wide variety of genres, such as pop, alternative, jazz, hip hop, electronic, and indie. Some of its most recent arrangements include songs from artists such as Jessie J, Coldplay, Taylor Swift, Billie Eilish and more. The group is very musically diverse and looks to expand its repertoire every year.
