"For his first album since Room(s) (and his debut for Ninja Tune), Stewart decided to write a concept album. Vapor City, illustrated by the grey-and-black industrial sprawl on the cover, is about an imaginary metropolis; each of its ten tracks is devoted to one of its districts. But if your eyes begin to roll at such a concept, fear not: Machinedrum's brand of mesmerism is its own instant attraction. Room(s) fans will find plenty to grab onto, from the rabid percussion and floor-bending bass of "Gunshotta," to the cathartic piano-laced footwork of "Infinite Us," or the speed-blurred vocals of "Don't 1 2 Lose U."".
