What is the last name of the person who always wanted more clarity?
Mahler made arrangements with the impresario Emil Gutmann for the symphony to be premiered in Munich in the autumn of 1910. He soon regretted this involvement, writing of his fears that Gutmann would turn the performance into "a catastrophic Barnum and Bailey show". Preparations began early in the year, with the selection of choirs from the choral societies of Munich, Leipzig and Vienna. The Munich Zentral-Singschule provided 350 students for the children's choir. Meanwhile, Bruno Walter, Mahler's assistant at the Vienna Hofoper, was responsible for the recruitment and preparation of the eight soloists. Through the spring and summer these forces prepared in their home towns, before assembling in Munich early in September for three full days of final rehearsals under Mahler. His youthful assistant Otto Klemperer remarked later on the many small changes that Mahler made to the score during rehearsal: "He always wanted more clarity, more sound, more dynamic contrast. At one point during rehearsals he turned to us and said, 'If, after my death, something doesn't sound right, then change it. You have not only a right but a duty to do so.'"For the premiere, fixed for 12 September, Gutmann had hired the newly built Neue Musik-Festhalle, in the Munich International Exhibition grounds near Theresienhöhe (now a branch of the Deutsches Museum). This vast hall had a capacity of 3,200; to assist ticket sales and raise publicity, Gutmann devised the nickname "Symphony of a Thousand", which has remained the symphony's popular subtitle despite Mahler's disapproval. Among the many distinguished figures present at the sold-out premiere were the composers Richard Strauss, Camille Saint-Saëns and Anton Webern; the writers Thomas Mann and Arthur Schnitzler; and the leading theatre director of the day, Max Reinhardt. Also in the audience was the 28-year-old British conductor Leopold Stokowski, who six years later would lead the first United States performance of the symphony.Up to this time, receptions of Mahler's new symphonies had usually been disappointing. However, the Munich premiere of the Eighth Symphony was an unqualified triumph; as the final chords died away there was a short pause before a huge outbreak of applause which lasted for twenty minutes. Back at his hotel Mahler received a letter from Thomas Mann, which referred to the composer as "the man who, as I believe, expresses the art of our time in its profoundest and most sacred form".The symphony's duration at its first performance was recorded by the critic-composer Julius Korngold as 85 minutes. This performance was the last time that Mahler conducted a premiere of one of his own works. Eight months after his Munich triumph, he died at the age of 50. His remaining works—Das Lied von der Erde ("The Song of the Earth"), his Symphony No. 9 and the unfinished Symphony No. 10—were all premiered after his death.
