War of the Worlds is a new opera that eliminates the boundary between concert hall and the streets of Los Angeles. Three defunct air raid sirens located in downtown Los Angeles are re-purposed into public speakers to broadcast the live performance, based on the infamous 1938 radio drama created by Orson Welles. Musicians from the Los Angeles Philharmonic will play on the stage of Walt Disney Concert Hall and broadcasted through the sirens onto the streets of Los Angeles — while performers stationed at the sirens will send their live report of the alien invasion back to the concert hall.
