In page Antonina Nezhdanova:

"

Nezhdanova made a number of recordings that display the beauty and flexibility of her voice and the excellence of her technique. She is considered by opera historians and critics to have been one of the finest sopranos of the 20th century.[citation needed] However, most of Nezhdanova's critical acclaim originates from Soviet-era sources, whose reliability is not always beyond question. Her sole appearance on the European stage—in Paris, 1912—was not particularly consequential in terms of either critical breakthrough or future professional engagement abroad. In his Soviet diary entry of February 6, 1927, Sergei Prokofiev observed: “Nezhdanova is already a middle-aged lady, very tall and very lovable. People say she is already losing her voice.” [1]
