European classical music is well represented in Argentina. Buenos Aires is home to the world-renowned Colón Theater. Classical musicians, such as Martha Argerich, Eduardo Alonso-Crespo, Daniel Barenboim, Eduardo Delgado, and Alberto Lysy, and classical composers such as Juan José Castro and Alberto Ginastera, and contemporary composers such as Osvaldo Golijov, Gerardo Gandini, and Oscar Edelstein are internationally acclaimed. All major cities in Argentina have impressive theaters or opera houses, and provincial or city orchestras. Some cities have annual events and important classical music festivals like Semana Musical Llao Llao in San Carlos de Bariloche, and the multitudinous Amadeus in Buenos Aires.
