‘Fidelio’ at Met gets a fill-in

Paul Nadler was named Monday to replace ailing James Levine as the conductor of the Metropolitan Opera’s revival of Beethoven’s “Fidelio.”

The production opens March 20, the same day Levine likely will have surgery to repair a torn right rotator cuff, an injury sustained when he fell onstage at Boston’s Symphony Hall on March 1. His estimated recovery time is three months.

Levine, 62, music director of the Met and the Boston Symphony Orchestra, will be replaced by Maurizio Benini as conductor of the Met’s new production of Donizetti’s “Don Pasquale,” which opens March 31.
