Leftfield are an electronic band formed in 1989 in London, United Kingdom. From 1989 to 2002, Leftfield was a duo of artists and record producers that consisted of Neil Barnes and Paul Daley. In January 2010, Barnes resurrected the band name and Daley has declined to be involved. They are pioneers in the fields of idm and progressive house, being among the first to fuse house music with dub and reggae.
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 (of Curve), who sang on “Original”, Djum Djum on “Afro-Left” and Earl 16 and Cheshire Cat on “Release the Pressure”.
"Open Up" is one of Leftfield's most famous tracks to date, featuring John Lydon (Johnny Rotten) of the Sex Pistols, released in 1993, this track withstands the test of time.
