Dubstep is the name given to the largely South London-based dark 2step sound that originally came out of productions by El-B (as part of both Groove Chronicles and the Ghost camp), Zed Bias (aka Phuturistix, Maddslinky and more) 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.

Largely this group is to further the sound of dubstep within the GTA and all of it surrounding areas
