Jesus Christ Superstar is a sung-through rock opera with music by Andrew Lloyd Webber and lyrics by Tim Rice. Loosely based on the Gospel accounts of the Passion, the work interprets the psychology of Jesus and other characters, with much of the plot centred on Judas, who is dissatisfied with how Jesus steers his disciples. Contemporary attitudes, sensibilities, and slang pervade the rock opera's lyrics, and ironic allusions to modern life are scattered throughout the depiction of political events; stage and film productions accordingly contain many intentional anachronisms.
Initially unable to get backing for a stage production, the composers released the score as a 1970 concept album, an immediate success which led to its Broadway stage debut in 1971. By 1980, the musical had grossed more than $237 million worldwide. Running over eight years in London between 1972 and 1980, the show held the record for longest-running West End musical until 1989 (overtaken by Cats).
