Continuum this week will present a special New Year's program of early music, both sacred and secular and also festive. The sacred music is primarily from the Manuscrit du Puy which brings together a varied group of Aquitanian monodic and polyphonic chants for the New Year from the 12th to the 16th centuries. The secular music will be spirited French estampie dances of the 14th century. Performing will be Ensemble Gilles Binchois, Theatre of Voices and Ensemble Tre Fontane.
