"Sviatoslav Richter amazed me by his spontaneity. I emphasize - the spontaneity of Richter's art of the 40's-50's is a unique phenomenon in pianism. For instance, today nothing is heard of spontaneity. And Emil Gilels has always been a mentor for me. I have always felt and still feel taken over by the wonder of Gilels' unique tone. Undoubtedly Richter and Gilels inspired me as magnificent virtuosos by their technique. The more so, as at that time I already had my own considerable technical achievements. In this respect everything was even too good, I would say."
