Looking for ‘Treasures’

Symphony Pro Musica’s celebratory 40th anniversary season continues with a program titled “Symphonic Treasures” with performances at 7:30 pm Feb. 4 at Hudson High School and 3:30 p.m. Feb. 5 at St. Mark’s School in Southborough. Guest violinist Maria Ioudenitch will make her Symphony Pro Musica debut, performing Beethoven’s Violin Concerto. “She is an extraordinary young Russian-American musician and one of the greatest rising violin stars performing today,” said Symphony Pro Musica’s founder and conductor, Mark Churchill. The program also includes Debussy’s Prelude to the Afternoon of a Faun, and Borodin’s Symphony No. 2. Churchill said Borodin’s symphony “used to be a staple of symphony concerts around the world.
