Video: Don’t Miss This Remarkable “Cup” Song

Anna Kendrick sang the original version of "When I'm Gone" in the hit musical, Pitch Perfect, a 2012 American musical comedy film directed by Jason Moore about a college women's a cappella group called The Barden Bellas, as they compete against another a cappella group from their college. The song has since seen many covers, including this one from Sam Tsui, Alex G, Kina Grannis, and Kurt Schneider. It's an impressive feat of percussion and vocal harmonies and you'll probably find yourself humming the tune long after it's over.
