Soprano Anna Netrebko needs shoulder surgery and has canceled performances in Verdi’s Nabucco at the Vienna State Opera. The 50-year-old was to have sung Abigaille on November 1, 6, 9, and 12, the first three with Amartuvshin Enkhbat in the title role and the last with Plácido Domingo. She says in a statement, “I have been suffering from debilitating pain in my shoulder for many months now and my doctor has advised me that I must undergo urgent surgery on my shoulder.” She says she will need physical rehabilitation following surgery.
