Leftfield was formed in 1989, before emerging publicly in 1990 with Not Forgotten, a song that established a template for a new strain of British house leaning away from American styles dominating UK clubs. Released in January 1995, their debut album Leftism remains one of the defining statements of dance music, a gloriously inter-woven bombardment of musical styles and immaculate grooves, nominated for a Mercury prize and later voted in the top ten greatest albums of all time by readers of Q magazine. The album spawned numerous hit singles in Open Up – their now legendary collaboration with John Lydon; Original, featuring Curve’s Toni Halliday; Release the Pressure, featuring Earl Sixteen; and Afro-Left, with vocals by Neil Cole, aka Djum Djum.

“It’s hard to overestimate the significance of Leftism, roundly acknowledged upon its release in 1995 as the first truly complete album experience to be created by house musicians and the first quintessentially British one” – Q Magazine
