Leftfield were a duo of electronica artists and record producers, Paul Daley (formerly of A Man Called Adam and the Brand New Heavies) and Neil Barnes, formed in 1989 in London, England. The name Leftfield was originally used simply by Neil Barnes for the first single Not Forgotten but after this Paul Daley was involved firstly in remixing songs and then in the creation of following music. The pair were pioneers in the fields of intelligent dance music and progressive house, being the first to fuse house music with dub and reggae [Release the Pressure (1995)].
