This week's program is an homage to the history and spirit of Notre Dame Cathedral in the wake of the tragic fire. We'll hear music composed by the two great representatives of the Notre Dame School, Leonin and Perotin, whose influence reaches all the way to our time. We'll also hear selections from a 13th century vesper service for Easter performed by the Gregorian Ensemble of the Maîtrise de Notre Dame.
