'Lost music re-born' said the BBC Music Magazine of 'Magister Leoninus 1' issued in 1997. That disc won a Diapason d'Or d'Année and appeared among the BBC's 'Best of the Year' discs. Here is a second CD of austere and beautiful music by this mysterious master from the 12th-century School of Notre Dame, of whose name we are not even sure. Red Byrd's new recording includes compositions for three of the most important feasts in the liturgical year: Christmas, Easter and Pentecost.
