Early on in Angelique Molina and Abraham Troen’s infectiously emotional musical documentary Just Sing, an interview subject explains that “Pitch Perfect made a cappella cool.” But for the members of the SoCal VoCals, a capella is about more than just having fun. Many of the students in the University of Southern California’s premiere vocal group are music majors, pursuing their dreams of stardom with boundless ambition and a relentless work ethic. This iteration of the VoCals is the most diverse in the group’s history, adding another layer of expectation from immigrant parents who have devoted their lives to their children’s success. Not to mention that the VoCals are competing for an unprecedented sixth win at the national collegiate championships in New York City!
