Schubert’s and Mendelssohn’s vivacity delight, while Schoenberg and a new work by a French composer fascinate. Schubert’s Rondo resembles a mini violin concerto with a virtuosic solo part, and Mendelssohn’s Octet has a bustling energy and beautiful melodies that make it his most popular chamber work. The West-Eastern Divan Ensemble, led by the orchestra’s concertmaster Michael Barenboim, bring its youthful energy to this remarkable music. The ensemble draws upon players of the West-Eastern Divan Orchestra—founded by Daniel Barenboim and the late Palestinian literary scholar Edward Said—to promote coexistence and intercultural dialogue by bringing young Israelis, Palestinians, and Arabs together to make music.
