Why are we still discussing Levine. The Met fired him. Levine has been replaced by Emanuel Villaume for all but one of the early performances of "Tosca," including December 31.
The first paragraph of the Vulture article @Moondance mentioned above. Moondance included the most important paragraphs. I am adding just one paragraph.
The investigations have begun, three victims have stepped into the light, and, while his crimes remain in the “alleged” column, James Levine’s career has clearly ended. If the now 74-year-old high priest of the Metropolitan Opera’s pit did what he has been credibly accused of doing, the principal casualties are his victims — three who have identified themselves, those who may soon do the same, and others who never will.
