Its simple, yet elegant text has inspired composers through the ages to depict the great mystery of the King of Kings born among humble animals and shepherds. This year the Rochester, NY chamber choir Madrigalia returns for another musical celebration of Christmas, centered on the O Magnum Mysterium Mass by 16th century Spanish composer Tomas Luis de Victoria.
