The Philadelphia Orchestra, which once had Riccardo Muti at its music director, has appointed Charles Dutoit, former conductor of the Montreal Symphony, to a four-year term as “chief conductor and artistic adviser.” The New York Philharmonic is said to be interested in Muti once again (though, to their credit, they may also be thinking about Alan Gilbert). The Chicago Symphony has also flirted with Muti (although focus is now shifting to Riccardo Chailly). A lot of this is a bit déjà vu, isn’t it? Next thing you know it will be time for the grand return of Zubin Mehta and Seiji Ozawa….
