William Jon Gray leads the Festival Chorale and members of the Festival Orchestra in a vivid program, which juxtaposes the brilliant high-Baroque Polychoral Mass in D Major by Ignacio de Jerusalem with 18th Century Christmas villancicos that have Spanish texts set to popular dance rhythms. The sophistication of the musical establishment at the Mexico City Cathedral in the Baroque Era was unrivaled in the Americas, and the elegant concerted vocal music of Chapel Master Ignacio de Jerusalem became widely performed \throughout California Missions.
