A performance by Anna Netrebko in the Czech capital Prague has been canceled. The announcement came after the Prague government said on Monday that all its coalition parties opposed the concert at a time Russia wages war on Ukraine. Prague’s Municipal House, where Netrebko’s Oct. 16 performance was to take place, and the Nachtigall Artists Management, an agency that organized it, have agreed on the cancellation. Netrebko, who will soon return to sing in Russia, won’t demand compensation.
