Russian-Austrian opera singer Anna Netrebko announced a forced break. The 54-year-old artist was scheduled to perform in Madrid but had to cancel her role in the opera "Il Trovatore" at the Teatro Real due to health issues. Doctors prescribed the opera singer a break. **Six Concerts, Six Countries** In her social media, Anna Netrebko wrote that six countries and six concerts with a large and quite challenging program in temperatures over 30 degrees for more than two weeks "absolutely exhausted" her resources. The singer clarified that to avoid harming her health and voice, she had to withdraw from the performance in "Il Trovatore." In it, Anna Netrebko performs the role of Leonora. After a medical examination, Anna Netrebko was advised to maintain "complete physical and vocal rest for the coming weeks," reports "Deutsche Welle." As is known, journalists often refer to her as the "favorite singer" of Russian President Vladimir Putin. The media has frequently linked her name with the prominent political and cultural support of the Russian leadership, although in recent years she has been living and building her career in Europe. Anna Netrebko has also visited Latvia. One of her most notable performances took place at the Opera Festival in Sigulda in 2000. Anna Netrebko sang in "The Marriage of Figaro," while she gave her role in "The Barber of Seville" to Elīna Garanča.
