Semyon Bychkov will be unavailable to conduct the New York Philharmonic’s performances at Alice Tully Hall, November 17–19. He will be replaced by Dima Slobodeniouk [pictured] in his New York Philharmonic debut. The program — featuring Shostakovich’s Violin Concerto No. 1 with soloist Karen Gomyo in her Philharmonic subscription debut and Tchaikovsky’s Symphony No. 1, Winter Dreams — remains unchanged.
