Directed by Dr. Mark Henderson, the program will feature a wide variety of Christmas works at the Holy Family Church. Among them will be excerpts from Britten's "Ceremony of Carols," Mark Henderson's work "The Mice in the Hay," Poulenc's "O Magnum Mysterium." There will be special numbers by the choir members, also. The concert has been an annual event since the origination of the Chamber Choir in 1990. The church itself was designed with performance of music in mind. It provides one of the most satifying settings, acoustically and visually, anywhere in Utah.
