New York Philharmonic executive director Zarin Mehta will take on the title of orchestra president, according to the ensemble’s board chairman. Mehta, who came to New York after leading the Chicago Symphony’s Ravinia Festival, was a major player in the search that led to the hiring of Loren Maazel as the Phil’s music director. Mehta’s day-to-day duties will not change with the new title – most American orchestra CEOs also carry the title of president – and the move appears to be largely a vote of confidence in his leadership at a time when the Phil faces several challenges.
