Just a few days after the Montreal Symphony, where Dutoit was music director from 1977 to 2002, could not confirm or refute allegations of his sexual misconduct there, management in Philadelphia, where Dutoit’s long relationship with the orchestra culminated in his 2008-12 tenure as chief conductor, stated that “our internal investigation found reports [of Dutoit’s misconduct] to be credible.” (The Philadelphia Orchestra, along with several others, cut all ties with Dutoit last December.)
