Two eras of heavy dubstep history, pressed onto one devastating piece of wax. On one side, Benga & Walsh team up for "Military"—a lean, mean, martial-steppers anthem built to march straight through a soundsystem. Turn it over, and Walsh & Kromestar trap you in the "Panik Room", delivering a masterclass in deep, claustrophobic bass weight and eerie, late-night minimalism.
