The Metropolitan Opera has scrapped its usual summer parks series and replaced it with one big, free concert this year. They booked husband-and-wife team soprano Angela Gheorghiu and tenor Roberto Alagna, who will sing arias and duets by Verdi, Puccini, Donizetti and Massenet in Prospect Park in Brooklyn on June 20, according to the New York Times. Ion Martin will conduct the concert, which will be streamed on the Internet and broadcast by local radio. Six wall-size screens will be placed in the Long Meadow, which can accommodate 150,000 people. Bank of America will provide 25,000 bus and subway passes for the event. While the Met’s operas in Manhattan’s Central Park featured Luciano Pavarotti in 1980 and 1988, and Placido Domingo in 1981 and 1987, few stars have appeared in recent years at the outdoor events. "The formula for the Met concerts in the parks had become somewhat routine," Met general manager Peter Gelb said Wednesday. "To make a parks concert not routine requires some major singing talent. In order to attract stars on the level on Angela Gheorghiu and Roberto Alagna, it’s necessary to present them with something that would be a vehicle they would be excited by."
