In May Gelb told the Associated Press that Zimmerman is to stage Bellini's La sonnambula, in a co-production with the Vienna State Opera, during the 2008-09 season. Booked for the title role is coloratura star Natalie Dessay, currently playing the titular madwoman in Zimmerman's Met Lucia.
"As far as I'm concerned," Gelb told the Tribune, "Mary is bringing so much to the art form of opera [that] ... if it's up to me and the Met, she will be creating as many productions here as she wishes to."
