The official statement says: "It is with great disappointment and regret that Anna Netrebko must cancel her Carnegie Hall recital debut scheduled for October 26. After singing seven performances of the extremely taxing title role in Donizetti's Anna Bolena at the Metropolitan Opera, she has been ordered to go on ten days of vocal rest by her doctor."
In a statement, Anna Netrebko said, "I love this program of music from my home country, and no one is more disappointed and frustrated than me that I won’t be able to perform for New York audiences next week. I apologize for any inconvenience this has caused and am deeply appreciative of everyone’s understanding of this difficult situation.”
