Dutch electronic music producer duo, RUR, has just released their latest techno single, "The Mad King." The EP includes two tracks, "The Mad King" and "Booster 500." "The Mad King" is a relentless bass-driven techno track, with well-balanced deep end and a dark atmosphere. "Booster 500" on the other hand is a hypnotic techno track with obscure synths and a narcotic beat.
