Roomful of Teeth is a GRAMMY-winning vocal project dedicated to mining the expressive potential of the human voice. Celebrity Series audiences got a taste of this ensemble’s particular brand of magic at last season’s Stave Sessions. At Sanders Theatre, Roomful of Teeth will be joined by Boston’s own 17-piece collective, A Far Cry in an innovative and exciting program that will include selections from Ted Hearne’s Law of Mosaics and Coloring Book, and Caroline Shaw’s arrangement of Josquin’s La déploration de la mort de Johannes Ockeghem and Music In Common Time.
