Wagner's concept of leitmotif and integrated musical expression has been a strong influence on many 20th and 21st century film scores, including such examples as John Williams's music for Star Wars and Howard Shore's soundtracks for Peter Jackson's three Lord of the Rings films. The rock composer Jim Steinman created what he called Wagnerian Rock. Heavy metal music is also said by some to show the influence of Wagner (as well as other classical composers). Joey DeMaio, the bassist and main composer for the heavy metal band, Manowar, has attested to Wagner's influence on his music.[8] In Germany Rammstein and Joachim Witt who has named three of his albums Bayreuth, claim inspiration from Wagner's music. Klaus Schulze (German electronic composer and Wagner admirer) dedicated his 1975 album Timewind to Wagner's death (two 30-min tracks, "Bayreuth Return" and "Wahnfried 1883"). He also used the alias Richard Wahnfried for a part of his discography. Andy DiGelsomina, composer of the forthcoming heavy metal opera, Lyraka, is also known to be an avid enthusiast of Wagner's music.[9][10] Most of Trevor Jones's soundtrack to John Boorman's Arthurian film Excalibur is from Wagner's operas. Adapted versions of Wagner's Ride of the Valkyries are used in the Francis Ford Coppola film Apocalypse Now and by Ennio Morricone in the western My Name is Nobody. An unusual manifestation of Wagner was in the 1957 Bugs Bunny cartoon film, What's Opera, Doc?, adapting music from various of his operas to fit in with the traditional topic of Elmer Fudd hunting Bugs.
