Rubinstein called. I played him the Myaskovsky Sonata, which he liked, but not excessively. My Tales of an Old Grandmother, however, pleased him enormously. 'They are so simple!' he said. I said I though I had called a halt to progress in the sense of searching for new paths. Rubinstein was delighted, and exclaimed: 'That is splendid! Believe me, whenever I see a composer deciding it is time to stop innovating, that is precisely the time he embarks on his new path.' I then played him Renata's hysterical scene, which sent him into ecstasy.
