Are cracks beginning to appear in the marriage between the New York Philharmonic and Carnegie Hall? Carnegie officials are looking forward: “People think that we are simply going to graft the current Philharmonic schedule on top of the Carnegie Hall schedule. The opportunity here is to create a merged institution that is forward-thinking. We are looking at new ways of presentation and new types of scheduling.” Forward-thinking. Sounds good. “Except that the Philharmonic, however splendid an orchestra, has not been forward-thinking since the 1970’s.”
