Dubstep is a genre of music which takes its name from the largely South London-based dark 2step sound that originally came out of productions by El-B (as part of both Groove Chronicles with Noodles and then the Ghost camp), Zed Bias, Horsepower and Steve Gurley in 1999-2000. Like another garage hybrid, grime, it uses dark sounds, but differs from grime in being largely instrumental. It also predates the evolution of grime by several years.
