The grand finale of the 2016 NY PHIL BIENNIAL features the Philharmonic and Alan Gilbert in music by two late, great Philharmonic friends: Messagesquisse for cello solo and six cellos by former Music Director Pierre Boulez, and Second Concerto for Orchestra by Pulitzer Prize winner Steven Stucky. Plus the U.S. Premiere of Per Nørgård’s Symphony No. 8 (listen for traces of Sibelius).
