The holiday concert, Christmas Through the Ages, will feature new arrangements of traditional carols “O Come, O Come Emmanuel” and “The Huron Carol,” as well as favorites like “Carol of the Bells” and “Sleigh Ride.” ProMusica Arizona will present the world-premiere of ProMusica Arizona Chorale member and professional composer Ryan Gunderson’s “Jesus, Refulsit Omnium“ (“Jesus, Light of All the Nations”), one of the first hymns in honor of the Nativity stemming from 368 A.D. As always, the audience will be invited to join in singing several well-known carols of the season.
