Dusky’s Nick Harriman and Alfie Granger-Howell do something that Londoners have been good at for some time. They make house music. Off an EP with the same name, ‘Cold Heart’ is unadulterated trance that borrows from the cavernous dance floors of the 1990s. The Hardrive-sounding sample is in fact Naked Music NYC’s ‘I’ll Take You to Love’ from 1996. The synthesised hi-hats, the simple bassline and the euphoria all sound eye-wateringly familiar.
