DUBSTEP

Dubstep is a genre of electronic music which has its roots in London's early 2000s UK garage scene. The genre's name was coined by Ammunition Promotions. Musically, dubstep is distinguished by its dark mood, sparse rhythms, and emphasis on bass. Dubstep started to spread beyond small local scenes in late 2005 and early 2006, with many blogs and forums devoted to the genre appearing on the internet. Simultaneously, the genre was receiving extensive coverage in music magazines such as The Wire and online publications such as Pitchfork Media.
