Rising star Gray returns to sub:stance after a big free download called ‘Junkie’ back in Autumn, with this filthy new single called 'Operate' - the label's first release of 2020. This track features Gray’s signature sound: it’s a dark filthy stepper with deep wobbling basses. Operate has been doing damage on the festival circuit last summer, being dropped by T>I, Saxxon, and others at festivals such as Illusive festival, among others.
