The accustomed Peter Gelb ballyhoo was not in evidence this morning when the Met very quietly let it be known that the company’s Parks concert series would not take place this summer. According to a rather modest item in today’s New York Times, in lieu of the familiar format of a “tour” of the city’s parks with complete operas in concert, the Met will present a single pops event on June 20 in Prospect Park featuring Roberto Alagna and Angela Gheorghiu.
