Almost eight centuries have passed since Maurice de Sully, Bishop of Paris, began the construction of the Cathedral of Notre Dame, one of the most magnificent centers of worship ever erected. At the same time, Notre Dame's composer Leonin completed his grandiose plan of providing polyphonic settings for celebration of the major liturgical feast days at the new Cathedral. Thirty years later his successor, Perotin expanded and enlarged on these works. These complex and pivotal compositions are performed to perfection by an exceptional vocal trio that is truly equal to the task, featuring the legendary countertenor Russell Oberlin, Charles Bressler and Donald Perry, tenors, with Seymour Barab viol, under the direction of Saville Clarke. Includes liner notes by William G. Waite, and full Latin texts with English translations.
