Jon Caramanca checks out the finals at Carnegie Hall: “There were groups striving to make a cappella their lives, groups that formed as passion projects and groups that seemed intent on dismantling the a cappella establishment from within by taking advantage of the competition’s open format to import styles of singing you won’t see at most college pre-frosh weekends. At times, and especially during the awards portion of the evening, that made for a confusing mandate, with global folk songs pitted against choral lite-gospel, and smarmy pop-rock alongside the familiar complex multipart vocal harmonizing (with vocal percussion!) that is a cappella’s public face.”
