For eight decades, musical history has been made at MEC, whether it was the American conducting debut of Pierre Boulez, world premieres of compositions by Igor Stravinsky, Arnold Schoenberg and Harold Budd, the early-career performances of future classical music icons such as Michael Tilson Thomas and Marilyn Horne, or the first Los Angeles appearances of artists like Marino Formenti, the Arditti and JACK Quartets and Steve Reich and Musicians. The ensemble has performed and premiered numerous works over the years.
