Formed in Massachusetts in 2009 under the direction of Brad Wells, a cappella octet Roomful of Teeth specialize in contemporary compositions that bridge classical, world music, and pop at their most virtuosic. Their first album, Roomful of Teeth, saw release in 2012 and won a Grammy for best small ensemble performance. Still going strong in 2020, they issued albums featuring the works of composers Wally Gunn and Michael Harrison.
