Four confirmed, veteran Ad Noiseam artists and a myriad of versions, edits and corrections ping-ponged between all of them. "Existence" and "Obey" are the carefully laid-out, detailled and fresh results of musicians having fun with each other's material and proving how at ease they are with both dubstep and drum'n'bass. DJ Hidden's sharpness, Broken Note's epic proportions, Niveau Zero's clever open-mindedness and Balkansky's meticulousness: yes they managed to pack all of this in these two highly cohesive tracks. A must-have for anybody into any of these acts.
