The Boston Artists Ensemble worked with Boston’s Beacon Academy — a 14-month school between 8th and 9th grades designed to prepare motivated and promising urban students for success in competitive independent high schools and beyond — to bring 24 students to our season finale. On the program was Messiaen’s “Quartet for the end of Time”, written when the composer was a prisoner of war in German captivity during WW2, and Schubert’s delightful “Trout” Quintet.
