This new Christmas CD Puer natus in Bethlehem, Alleluia! on CBC Records features not only a fascinating array of Christmas choral music but is also the premiere recording of the Elmer Iseler Singers under their new artistic director, Lydia Adams. Taking the ancient Piae Cantiones plainsong melodies of medieval origin as the inspiration for this CD, the Elmer Iseler Singers have fashioned new and fresh arrangements by many of Canada’s finest composers. Puer natus in Bethlehem, Alleluia! takes the listener into a sound world of both quiet contemplation and sparkling energy, combining through glorious choral music the spiritual connection and joyous celebration of this most important holiday season.
