There will be beat boxers, gospel singers, barber shop quartets and college kids singing this weekend at Montreal's 3rd annual MTL a cappella festival.
It's happening at the Théatre Paradoxe, a refurbished church in Ville Emard.
Director Michael Dyck says the diversity of groups is what makes Montreal's festival unique.
"There are other a cappella festivals, especially in the U.S., it's quite popular, but they usually find either only barber shop or either only collegiate style a cappella," he said.
"Montreal a cappella is really unique in that we bring together all sorts celebrating the diversity of the city."
A cappella means singing with no instrumental backing.
Dyck discovered a cappella while studying physiotherapy at McGill, when he joined the group, Effusion.
"I didn't know what to expect and was soon swept off my feet," he said.
The festival features a number of performances and workshops including: how to beat box, how to arrange for female voices, how to use a loop, Georgian singing, and the business aspects of running an a cappella group.
It's all taking place in a new venue, the refurbished l'Église Notre-Dame-du-Perpétuel-Secours in the Ville-Émard borough.
The weekend line-up includes Montreal's women's choir, Choeur Maha, the Choeur international de Montréal, VoiceMale an award-winning all-male a cappella group from Brandeis University, Westmount's Burton Street Singers, and Minor Adjustments, the only co-ed, all-vocal group on campus at SUNY Plattsburgh.
MTL acappella runs May 9 to 11.
