Task: Question Generation
Input (English): Passage: In 1924, Monteux began a ten-year association with the Concertgebouw Orchestra of Amsterdam, serving as "first conductor" ("eerste dirigent") alongside Willem Mengelberg, its long-serving chief conductor. The two musicians liked and respected one another, despite the difference in their approach to music-making: Monteux was scrupulous in his adherence to a composer's score and straightforward in his performances, while Mengelberg was well known for his virtuoso, sometimes wilful, interpretations and his cavalier attitude to the score ("Ve vill make some changements", as an English player quoted him). Their preferred repertoire overlapped in some of the classics, but Mengelberg had his own favourites from Bach's St. Matthew Passion to Mahler symphonies, and was happy to leave Debussy and Stravinsky to Monteux. Where their choices coincided, as in Beethoven, Brahms and Richard Strauss, Mengelberg was generous in giving Monteux at least his fair share of them.While in Amsterdam Monteux conducted a number of operas, including Pelléas et Mélisande (its Dutch premiere), Carmen, Les Contes d'Hoffmann, a Lully and Ravel double bill of Acis et Galatée and L'Heure espagnole, Gluck's Iphigénie en Tauride (also brought to the Paris Opéra) and Verdi's Falstaff. Toscanini had been invited to conduct the last of these, but he told the promoters that Monteux was his dearest colleague and the best conductor for Falstaff.During the first eight years of his association with the Concertgebouw, Monteux conducted between fifty and sixty concerts each season. In his final two years with the orchestra other conductors, notably the rising young Dutchman Eduard van Beinum, were allocated concerts that would previously have been given to Monteux, who amicably withdrew from his position in Amsterdam in 1934. He returned many times as a guest conductor.
Output (English): What is the full name of the rising conductor that was given concerts usually given to the man who conducted between fifty and sixty concerts each season?
