Roomful of Teeth is an experimental choral group founded and directed by Brad Wells a few years ago. Their music makes use of an array of singing techniques. Not only does the group have a strong set of beautiful singing voices, but they’re not afraid to segue into stints of throat singing, screams, or loud gasps.

This new, self-titled album of theirs was created via a series of guest composers. Among them is actually Merrill Garbus of tUnE-yArDs. Her contribution can be heard on the extremely chilling “Quizassa.”
