The group includes well-known conductors such as Daniel Barenboim, Roberto Abbado, Lorin Maazel, and Riccardo Chailly, as well as emerging talents such as Daniel Harding, Vladimir Jurowski, and Gustavo Duhamel.
Harding will conduct Idomeneo on the company's opening night in December.
In a press conference on July 21, La Scala general director St_phane Lissner said that the opera company would begin a new direction, a "fresh artistic impulse."
Muti, who directed La Scala's orchestra for 19 years, resigned in April, following a long standoff with musicians and La Scala employees who were angry about what they felt to be his part in the firing of then-general manager Carlo Fontana.
"You don't replace Muti in a month or in a year," Lissner said. "It's impossible to replace a conductor of his ability. If a replacement exists, he's not available."
Lissner also said that his priorities for La Scala are to "give back the sense of a big artistic impulse, get back to economic rigor, and ensure social cohesion in the house."
