Muhly fell in love with Byrd’s setting of the Christmas words Senex Puerum Portabat as a chorister, so much that the ‘fluidity of the lines, the relentless lilting rhythm, and the way Byrd both avoided and cradled the text’ that he was inspired to follow a life in music. Early in his career, he set the same text in modern style. The first statement of the words is a capella with ecstatic brass entering in the restatement. The ancient Hodie Christus Natus Est follows on seamlessly in a new mood.Contemporary American composer Nico Muhly is a prolific writer and arranger who, at 32, is the youngest composer ever to have been commissioned by the Metropolitan Opera in New York.
