According to the Bayerische Staatsoper, Anna Netrebko will not appear there in Manon Lescaut, and has been replaced by Kristīne Opolais, who in turn has been replaced at the Met in La Bohème by Sonya Yoncheva.
From the Bayerische Staatsoper management: “We would still like to thank Anna Netrebko for deciding at an early
stage that, due to differing artistic perspectives on the work, she
would prefer to pull out."
She resigned because of the production. Wow. This is a different production from the full on pornographic production at the Royal Opera, but we can only speculate that it was similar. They have chosen to prefer their production to her. She is easier to replace than it. A lot of people are going to be angry because this is all sold out.
There are no hints so far of what the production will look like.
Netrebko has agreed to sing Tatiana for them next summer.
P.S. There is an interview with Hans Neuenfels in the recent Der Spiegel. Basically he says they have had an artistic disagreement. Neuenfels wants Manon to unambiguously choose between these two widely different lives, the poor student or the rich old man, while Netrebko believes that she holds both ideas dear in her mind at once. Neuenfels ridiculed this idea. Obviously he isn't a woman. He may also never have lived in extreme poverty as Netrebko has. Jonas thinks (other source) that there were language problems between the two of them. Neuenfels wants to make clear that he and Netrebko are not angry with one another.
