Emocapella (a portmanteau of emo and a cappella) is a collegiate a cappella group at the George Washington University, formerly all-male but co-ed since 2010. Emocapella was founded in October 2001 by Eric Denman and Dan Riesser, GW sophomores at the time, who wanted to form a group that purposefully deviated from traditional a cappella. The group's first performance was in December 2001, opening for another GW a cappella group, the Vibes. They were invited by Taking Back Sunday in December 2002 to perform at their opening act.
