“..The quartet of soloists was also added by twenty-six-years-old Russian mezzo-soprano Margarita Gritskova, who used to work for three seasons at the National Theatre in Weimar until recent invitation to the Vienna State Opera troupe. Attractive black-haired young woman showed her agreeable languid voice singing arias from "The Barber of Seville" by Rossini and Habanera from "Carmen" (then a comic ballet performance with the hand fan was also presented to the public). Gritskova also starred as a proud Spaniard in a spectacular and hilarious African Duo from zarzuela by Caballero. In contrast to the restrained Anita Hartig, the singer has appeased neither singing passion nor any other. It seemed that her partner - of course, again Carreras - does not want to approach her, fearing that it will blow him out..."

"Margarita Gritskova (mezzo-soprano) scored in the Rosina’s area „Una voce poco fa” („A voice a while back”) from Rossini’s „ Barbiere di Sevilla” with the excellent coloraturas. She proved her talent both at singing and acting in the area „Habañera” from the opera „Carmen” by Georges Bizet. She is a talented junior artist and in the future it will be for sure more to come!"

"Then came turn of Margarita Gritskova, a mezzo-soprano singer, who performed perfectly at ease Carmen’s Habanera with a fan in her hand. But later she surpassed herself in her acting, while performing duet and jota from zarzuela “El Duo de "La Africana" with Jose Carreras: a magnificent version, charming, but fun at the same time. The audience really enjoyed such full interpretation, impressive both vocally and on the level of recitative. An outstanding abundance of mezzo-soprano, as well as participation of the artist of the highest level, such as Carreras, has become key components of the huge success of this beautiful duet."
