Leftfield are a British duo of electronica artists and record producers, namely Paul Daley (formerly of The Rivals, A Man Called Adam and the Brand New Heavies) and Neil Barnes, who formed in 1990 in London, England. The name Leftfield was originally used simply by Barnes for its first single with editing/arranging and additional production added by Daley "Not Forgotten", but after this, Daley was involved in remixing "Not Forgotten" and then in the creation of all Leftfield''s music. The pair were pioneers in the fields of intelligent dance music and progressive house, being among the first to fuse house music with dub and reggae. Ultimately the duo have been influential on the electronic genre as a whole, with The Crystal Method''s Scott Kirkland referring to them in 2005 as "the best electronic band, period!" As with many of their contemporaries such as The Chemical Brothers and Underworld Leftfield pioneered the use of guest vocalists throughout their career. Among the more prominent were Toni Halliday, who sang on Original, Djum Djum on Afro Left and Earl 16 and Cheshire Cat on Release the Pressure. As of December 2011, Neil Barnes continues to tour with the band while Paul Daley is focusing upon his solo career.
