Conductor Robert Spano (Conducting ’85) reunites with “force of nature” Yefim Bronfman (Piano ’77) to perform Béla Bartók’s ferocious Second Piano Concerto. Bronfman, a recent addition to the Curtis faculty, won a GRAMMY Award for his recording of the concerto. The program continues with Tchaikovsky’s brooding Fifth Symphony. In this work, resolve and sweeping optimism clash against bouts of steely melancholy.
