From a rare new interview with the Russian pianist and conductor:
Do you read reviews of your concerts?
Why do you prefer to sit in a chair at the piano and not on a stool?
– Back ache. If I get tired – I can lean back and relax a bit.
Do you go to concerts of other artists? If so, which ones?
– I do not go.
– Did you watch the last Tchaikovsky Competition?
