NEW YORK - New York's Metropolitan Opera announced Monday it fired legendary conductor James Levine, for decades the face of its orchestra, after finding "credible evidence" that he sexually abused younger musicians.

The leading US opera house had already suspended Levine in December after allegations first became public against him. Levine guided the MET's orchestra for 40 years as music director.

The MET said it has "terminated its relationship" with Levine, who retired in 2016 amid failing health but until the scandal had remained a frequent presence as a conductor.

"The investigation uncovered credible evidence that Mr. Levine had engaged in sexually abusive and harassing conduct both before and during the period when he worked at the MET," the opera house said in a statement.

The three-month investigation concludes a spectacular fall from grace for a musician often hailed as one of the top US conductors of his generation.

Fittingly perhaps, his final MET appearance was conducting Verdi's "Requiem" in December.

The opera house said it was "committed to ensuring a safe, respectful and harassment-free workplace for its employees and artists."

The MET, however, also absolved itself of blame after criticism that it could have acted before longstanding allegations about Levine made headlines amid the growing spotlight in the United States on sexual abuse by powerful men.

"Any claims or rumors that members of the MET's management or its board of directors engaged in a coverup of information relating to these issues are completely unsubstantiated," it said.

The MET, which like many major US music institutions has a constant challenge of shoring up its finances, has acted quickly to move past the taint of Levine.

It has brought forward the appointment of Levine's successor, youthful French Canadian Yannick Nezet-Seguin, who will become music director with the upcoming season.

Levine, 74, was said by younger musicians to have sexually abused them when they were vulnerable students and he was the charismatic visiting instructor, with most cases dating decades ago.

In an investigative piece published this month by The Boston Globe, former students at the Cleveland Institute of Music described Levine as a cult-like figure who not only coerced them into sex but controlled their lives.

Quoting former students, the newspaper said that Levine would pressure them to cut off ties with the outside world and pledge loyalty to him as he led meetings that involved everything from studying opera scenes to anonymous sex.

Levine's downfall began in December, when the New York Post reported on a 2016 police report in which a teenager alleged decades of abuse by the conductor starting when the victim was 15 at the Ravinia Music Festival near Chicago -- one of a number of classical institutions that has since cut ties with Levine. - AFP
