"I decided then and there that the symphonies of Beethoven and Brahms were the only music for me, not the music of this crazy Russian. … My one desire was to flee that room and find a quiet corner in which to rest my aching head. Then Diaghilev turned to me and with a smile said, "This is a masterpiece, Monteux, which will completely revolutionize music and make you famous, because you are going to conduct it." And, of course, I did."
