Context: The largest opera houses of Paris are the 19th-century Opéra Garnier (historical Paris Opéra) and modern Opéra Bastille; the former tends toward the more classic ballets and operas, and the latter provides a mixed repertoire of classic and modern. In middle of the 19th century, there were three other active and competing opera houses: the Opéra-Comique (which still exists), Théâtre-Italien, and Théâtre Lyrique (which in modern times changed its profile and name to Théâtre de la Ville). Philharmonie de Paris, the modern symphonic concert hall of Paris, opened in January 2015. Another musical landmark is the Théâtre des Champs-Élysées, where the first performances of Diaghilev's Ballets Russes took place in 1913.
