Celebrating Berkshire Bach Society’s 25th anniversary, James Bagwell will conduct Vivaldi's vibrant setting of the "Gloria," along with Mozart's instrumental masterpiece, “Sinfonia Concertante,” two shorter choral works by Mozart, and a hidden gem by Zelenka, the “Magnificat.” Violinist Helena Baillie and violist Marka Gustavsson join the Bard Baroque Ensemble for this performance. A chorale of eight professional soloists includes mezzo-soprano Teresa Buchholz.
