".."Concert was a spectacular event due to Gritskova. " (..) At the concert, Carreras decided to sing with Russian mezzo-soprano Margarita Gritskova. The fact that the evening turned into the spectacular event was also her merit. Since the 2012/13 season, Ttwenty-seven-years-old Russian singer is a soloist of the Vienna State Opera, she made her debut in the summer at the Salzburg Festival as Cherubino in "The Marriage of Figaro" by Mozart. The volubility with which Gritskova performed the Brucknerhaus "Canción de Paloma" in front of the audience has been truly remarkable."

"Some changes into the program brought the Russian Margarita Gritskova (mezzo- soprano) with the works of Rossini, Debussy, Rachmaninov, etc.; she was brilliant with her pitches, both as the soloist and in the duet with José Carreras. The instrumental accompaniment, unusual and initially in need to be familiar, consisted of the pianist Lorenzo Bavaj and a string quartet. The restrained applause at the beginning grew louder – as awaited – by the five encores which José Carreras and Margarita Gritskova sang both solo and together. Properly, the audience left the opera house with „lips fall quiet” from „The Merry Widow”."

".. Franz Schubert’s „Ave Maria“, performed in Duet with Margarita Gritskova (27), leads not only now to another world. Beautiful voice and much temperament – that was a marvelous idea to have a rising star at mezzo-sky – with a huge career leap for Vienna and this year for The Salzburg Festival – on this evening by the side. Beautiful voice, temperament at her appearance, coquetry and sensuous charisma were her trump cards at singing the best masterpieces to raise the spirits of great Masters."
