Futuristic beatsmith and expansive producer Jamie xx has spent years racking up glittering collaborations with the likes of Drake and Young Thug, lending his off-kilter remixes to Adele and even his own band The xx. But he doesn't need famous names to impress: “Gosh”, with its '90s-indebted, shuffling drum ‘n' bass drive, is a master class in minimalist synth-pop, while Alicia Keys' “When It's All Over” —which the South Londoner co-produced—nods to his knack for weaving filthy basslines under sublime female vocals.
