Boston Sings [BOSS] A Cappella Festival 2026

Taking place in and around the city of Boston, BOSS is a three-day event featuring everything you’ve come to expect from an a cappella festival and more: an innovative spin on the scholastic competition on Friday, a day of workshops, masterclasses and SoundBites, and a professional concert on Saturday night. The exclusive LIVE presentation and announcement of the Contemporary A Cappella Recording Awards closes the festival on Sunday (ticketed separately).
