A drum ’n’ bass ambassador to the wider electronic scene, Sub Focus made his name with his blazingly technical productions of the 2000s, then leveled up by infusing his anthemic style with elements of dubstep and house. The London DJ’s roots show through in the rolling breaks of 2009’s emotive “Last Jungle”; by contrast, 2019’s “Siren” displays his dazzling studio chops in swaggering grooves and incandescent synths. But unlike many junglists, Sub Focus has never stuck to one lane: consider the slyly futuristic hip-house of 2013’s “Turn Back Time” or the dreamy tropical house of 2017’s “Don’t You Feel It.”
