"In the beginning, Olga is a playful, vivid girl interpreted by the Russian mezzo-soprano singer Margarita Gritskova. She was great on the stage, performed the way it must be performed, and in her voice you could find a variety of tones. She has the charm and skillfully uses it. The viewer’s attention is stuck to her so that her sister Tatiana remains in the shadow.”
Jacques Hétu, ResMusica, 25 oct.2011

"The nature gave Margarita Gritskova, the Russian mezzo-soprano singer, a very rich tone of voice. In the first act she was a real Carmen, who popped in the house of Olga Larina.”
Richard Boisvert, Le Soleil (, 24 oct. 2011
