Jonas Kaufmann has not only cancelled Walkure at the Met, but the Jonas Kaufmann Gala in Zurich is also cancelled. The only thing I can find out is that he has a trachea infection. Let's hope for the best.
The Opernhaus Zürich has announced that May 11 will be a recital by Edita Gruberova and May 13 will be a Leo Nucci Gala. Nucci's gala will consist of three acts from Verdi: Act II of La Traviata, Act II of Rigoletto and Act III of Simon Boccanegra. Piotr Beczala will be there for Traviata and Rigoletto. It sounds like fun.
