At the concert I was sharing a box with N.K. [Natalya Koussevitzky] and Borovsky. We were on tenterhooks for Stravinsky: suppose he got completely lost? 'He's like a girl about to lose her virginity,' I observed. His entrance on to the stage showed how much he was on edge, but the ovation he received gave him courage. He had a copy of the score beside him on the piano stool in case of an emergency, but he played well, with élan and without obviously coming off the rails. THe success was tremendous, as well it might be, a forty-year-old composer unexpectedly debuting as a pianist, and such a dashing one too. It was as if I were to appear playing a solo on the bassoon! The Concerto is certainly not easy to play, even if it does have passages of no great interest pianistically speaking. But I do not care for the imitative style of the music with its plethora of pilferings, even if they are from the ancients.
