Maazel was to conduct Ring Without Words, his own orchestral arrangement of Wagner's Ring cycle, on May 11, 12, 13, and 14. According to the Cleveland Plain Dealer, the performances would have been his first with the orchestra since he stepped down as music director in 1982.
Giancarlo Guerrero, the music director of the Eugene Symphony, will step in for Maazel.
Maazel led the Netherlands premiere of Ring Without Words at the Concertgebouw in Amsterdam on May 6. According to the Cleveland Orchestra, the ear infection prevents him from flying back to the United States.
He is scheduled to conduct the New York Philharmonic, of which he is music director, for two weeks starting May 24. A spokesperson for the Philharmonic said Maazel was expected to recover and appear as scheduled.
