Marcel Pérès founded Ensemble Organum in France in 1982, and since then the group has become an outstanding source of unique chant and polyphony. We'll sample several of my favorite Ensemble Organum recordings in this episode, including Chant of the Knights Templar, the Gradual of Eleanor of Brittany, and polyphony from 12th century Aquitaine.
