Mood Swing A Cappella has been performing across the Claremont Colleges since 2004, comprised of members from each of the five schools. In their distinctive black and yellow attire, the group brings their voices together on in-house arrangements across a variety of genres, ranging from radio pop throwbacks, indie gems and jazz-touched classics.

The group's ethos resonates in their legacy song, “A Change in My Life” from Rockapella. Year to year, the members of Mood Swing come together for the music, but stay for the friendship.
