Description"Devolution Theory" brilliantly flirts with the sound you've been secretly loving lately but were scared to admit. Deep and driving but also floaty, emotive, it reminds you of classic progressive that's chuggy yet tight as a gnat's chuff, and you love it. "Axe Grinder" is chuggy too, yet more bittersweet. Did we mention that both tracks are solidly built for the main room? Mariana is a game of two halves, with resident DJ at Bristol's legendary Empathy night, Adam Kent and production maestro Bailey. Designed to be an outlet for their combined love of deep, trippy tech house, the project is suitably named after the deepest ocean trench in the world: Mariana.
