As their name suggests, Leftfield unearths house music’s most progressive strains. Originally the lovechild of Neil Barnes and Paul Daley, the English group—which turns 30 this year—released its influential ‘Leftism’ album in 1995, featuring genre-transcending contributions from the Sex Pistols’ John Lydon, among others. After a decade of significant influence and critical acclaim, Leftfield went on hiatus in the 2000s, returning as the solo project of Barnes in 2010. Known for their high-intensity live sets, Leftfield is also infamous as the band that was officially banned from London’s Brixton Academy for causing dust and plaster to fall from the venue’s ceiling. Their ambient-leaning ‘A Final Hit’ is widely known—can we get any more nostalgic?—for its sonic role in ‘Trainspotting’.
