Voices in Your Head is a student-run, co-ed a cappella group from the University of Chicago. Founded in 1998 by Amanda Grossman, the group consists of both undergraduate and graduate students whose studies range from Economics to Music to MD/PhD programs. Voices arranges all of its own music, spanning several genres. Its unique repertoire includes original pieces, as well as an eclectic mix of pop, R&B, rock, and alternative music. Voices competes annually in the International Championship of Collegiate A Cappella (ICCA), and travels nationally for a cappella festivals and tours.
