Dubstep originated in South London in the late 1990s, developing from genres like 2-step garage, drum and bass, and dub reggae. Early dubstep releases from 1998 featured darker, more experimental remixes with less vocals that incorporated elements of breakbeat. The term "dubstep" emerged around 2002. Key characteristics include wobble bass lines created by manipulating extended bass notes, as well as bass drops inherited from drum and bass. Dubstep tracks typically have an intro, main sections with drops, midsections, and outros. Popular dubstep artists include Skrillex, Flux Pavilion, Chase & Status, and Sub Focus.
