For nearly 50 years, the Philadelphia Orchestra was the orchestra-in-residence for the Ann Arbor May Festival. They performed in Hill Auditorium first in 1913, shortly after the hall opened, and most recently in 1994. Music Director Yannick Nézet-Séguin brings the orchestra back to Ann Arbor with a stunning program: a suite from Nico Muhly’s sensational opera Marnie, which receives its US premiere this fall at the Metropolitan Opera; Rachmaninoff’s Symphonic Dances, the composer’s final piece, written for the Philadelphia Orchestra in 1940; and Tchaikovsky’s spectacular Violin Concerto, performed by the Georgian violinist Lisa Batiashvili in her UMS debut.
