There have been many groups who have contributed to the current revolution of jaw-dropping, innovative, earth-shattering a cappella music.
But hands down, one of the key players in recent years is Voices In Your Head from the University of Chicago. Whether it's blending cutting-edge vocal effects with methodical choreography, or their interpretations of current pop music that transcend anything we've seen in this art form, Voices In Your Head is an act that can't be ignored.
And their second place performance at ICCA Finals on April 22nd further speaks to their greatness.
Take a look at the set that earned them second place as well as an "Outstanding Arrangement" in New York City with covers of Diplo, Calvin Harris, and Beyonce to name a few in the video below.
