Today we continue our perusal of the sacred repertoire of Adrian Willaert, with his O Magnum mysterium, which he composed for the 4th responsorial for the Office of Matins on Christmas Day.

This performance is by the Cappella Marciana, Marco Gemmani – conductor.

At 5 P.M., FromRome.Info brings you a selection of sacred music from Catholic composers throughout the ages, for your edification and to help us all realize how profoundly inimical the Aggiornamento has been to Catholic worship.
