The New York Philharmonic will travel to the Soviet Union in late May for 10 days of “symphonic summitry” coinciding with President Reagan’s summit talks with Soviet leader Mikhail S. Gorbachev, orchestra and Soviet officials announced late last week. The orchestra will be performing in Leningrad while Reagan and Gorbachev are meeting in Moscow, and neither leader was expected to attend a concert during their five-day summit, officials said. The Philharmonic, making its first Soviet tour with music director Zubin Mehta and only the third in its 146-year history, will travel to Moscow for a series of concerts starting June 4, two days after the Reagan-Gorbachev talks officially end.
