Mastersingers present “Gloria” — Central Oregon Mastersingers will perform Christmas-themed works at 7:30 p.m. Saturday and 2 p.m. Sunday at the Tower Theatre, 835 NW Wall St., in Bend. The concert opens with music from the Baroque period, including Antonio Vivaldi’s “Gloria.” Mastersingers director Christian Clark notes that Vivaldi’s famed, 300-year-old piece is a great introduction to classical music that didn’t enjoy widespread popularity until the mid-20th century. “Carol of the Bells,” features a string orchestra and local pianist Scott Michaelsen; “Silent Night,” “Joy to the World” and an array of other Christmas carols round out the program — which also includes an audience sing-along. Tickets are $17 to $32 at, or call 541-317-0700.
