"The Ecstasy of Gold" (Italian: L'estasi dell'oro) is a musical composition by Ennio Morricone, part of his score for the 1966 Sergio Leone film The Good, the Bad and the Ugly. It is played while Tuco (Eli Wallach) is frantically searching a cemetery for the grave that holds $200,000 in gold coins. Sung by Edda Dell'Orso, it stands as one of the most well known of Morricone's themes. American metal band Metallica has used "The Ecstasy of Gold" as the introductory music for its concerts since 1984. New York City-based punk rock band Ramones used this theme as the outro music for their concerts since 1991.
