Musical genres abound in this eclectic Mass setting from Norah Duncan, IV. From the calypso feel of the Gloria to the early American character of the Gospel Acclamation to the gentle lyricism of the Lamb of God, this variety of styles comes together beautifully into an inspiring setting that has the power to unite the most diverse assembly. Brass quartet and timpani parts are optional. Horn in F can be substituted for Trombone I.
