0806met.jpgEach summer the Met offers a free outdoor performance, and the one-night-only event is going down in Prospect Park later this evening. Two of the opera world's biggest stars, Angela Gheorghiu and Roberto Alagna, will be belting out duets as Ion Marin conducts the Metropolitan Opera Orchestra and Chorus.

Fun fact: Gheorghiu and Alagna were married backstage at the Met during a run of La Bohème in 1996...by Giuliani!

Head over to the park (there's a map after the jump) for the evening of open air arias (the weather is good for it) -- the performance is at 8 p.m. Read up on the preparation that went into the event at the NY Times, who also add that The Met chorus will be donning costumes designed by Isaac Mizrahi.
