From the historic Spanish Riding School at Vienna’s Hofburg Palace. Accompanied by longtime collaborator Pavel Nebolsin on the piano, the celebrated soprano offered a program of ravishing Russian songs, operatic arias, and music by Strauss, Debussy, Fauré, and more. Later on in the evening, mezzo-soprano Elena Maximova joined Netrebko for a pair of duets from Tchaikovsky’s The Queen of Spades and Offenbach’s Les Contes d’Hoffmann. For Met audiences familiar with Netrebko’s gutsy portrayals of opera’s most formidable heroines, this concert offered a more intimate look at one of today’s most extraordinary talents.
