The Nuns of the Abbaye de Notre-Dame de l'Annonciation, from a remote region of France near Avignon, won a worldwide search to find the world's finest female singers of Gregorian Chant. The search took in over 70 convents, including communities as far afield as North America and Africa. The Nuns' album features the most ancient form of Gregorian Chant, which the sisters sing eight times a day, and was the first music ever to be written down.
