AOR was a performance by Jean Michel Jarre. Jarre became the youngest musician to see one of his works played at the Paris Opera, at its reopening on 21 October 1971. The reopening consisted of three ballets; the first and third ballet were set to classical music, AOR - the second ballet that night - was completely electronic. It was the first time that electronic music had been allowed to be used. Jarre even had to paint the speakers of his synthesizers gold to match the decor of the opera house. There he performed with the Paris Opera Ballet, choreographer Norbert Schmucki and musician Igor Wakhévitch, who co-wrote the music.
Jarre composed the music for two additional ballets: Le Labyrinthe (1972) and Dorian (a pas de deux) (1973), but it is currently unknown if he performed them as well.
