The answer to the question: What is the name of the person that said "I did not like Le Sacre then. I have conducted it fifty times since. I do not like it now."? is inside the article: During the 1913 Ballets Russes season in Paris, Monteux conducted two more premieres. The first was Jeux, with music by Debussy and choreography by Nijinsky. The choreography was not liked; Monteux thought it "asinine", while Debussy felt that "Nijinsky's cruel and barbarous choreography ... trampled over my poor rhythms like so many weeds". The second new work was Stravinsky's The Rite of Spring given under the French title, Le sacre du printemps. Monteux had been appalled when Stravinsky first played the score at the piano: 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. Despite his initial reaction, Monteux worked with Stravinsky, giving practical advice to help the composer to achieve the orchestral balance and effects he sought. Together they worked on the score from March to May 1913, and to get the orchestra of the Théâtre des Champs-Élysées to cope with the unfamiliar and difficult music Monteux held seventeen rehearsals, an unusually large number. Monteux's real attitude to the score is unclear. In his old age he told a biographer, "I did not like Le Sacre then. I have conducted it fifty times since. I do not like it now." However, he told his wife in 1963 that the Rite was "now fifty years old, and I do not think it has aged at all. I had pleasure in conducting the fiftieth anniversary of Le Sacre this spring"., can you guess it ?
