"Nella Fantasia" first appeared on Sarah Brightman's album Eden (1998). A music video for the song was released on Brightman's Diva: The Video Collection in 2006 and the song sold 2 million digital copies in South Korea.In the liner notes of Eden, the lyricist of the song was named as "Ferraù". In a review of a Sarah Brightman concert at the San Jose Center for the Performing Arts on 14 September 1999, Philip Anderson wrote that "'Nella Fantasia'... was inspired by an instrumental soundtrack for the film, The Mission, which Sarah had begged the composer to allow her to put lyrics to". It is possible that Brightman wrote the lyrics of the song in English and they were translated into Italian by Ferraù. Confusingly, the liner notes of Brightman's subsequent album The Very Best of 1990–2000 (2001), which also featured the song, state that the composers of the song were Berta Ferraud and Ennio Morricone. It may be that "Berta" is a nickname and "Ferraud" a misspelling of "Ferraù".
