This is a fine collection of unaccompanied music from some of the master's of the golden age of polyphony. Missa Ave Regina Coelorum (c.1464) is Dufay's crowning achievement and we know that Dufay requested that this Angus Dei be sung on his deathbed. Crucifixus was originally intended for solo voices, but is transcribed here for four-part male chorus. It may be sung effectively by solo voices, chamber choir, or full chorus. Everybody's repertoire should include some examples of this early music style and are both fun and interesting to perform. This music has been sung for 500 plus years and still continues to please!
