The first of three Marlboro Music tour programs this season features nine musicians performing works from three centuries. Respighi’s rarely performed Il Tramonto for voice and string quartet is a work that tells the story of two lovers and their tragic fate. Rene Orth’s You Shattered My Deafness incorporates text by St. Augustine in a reflective work. The evening ends with the chamber music work: Mendelssohn’s String Octet, a piece brimming with energy and beautiful melodies.
