Roll Deep are a British grime crew. They were founded in 2001 by Wiley shortly before the disbandment of UK garage crew Pay As U Go Cartel.

Grime is a genre of electronic dance music (EDM) that emerged in London in the early 2000s. It developed out of the earlier UK dance style UK garage, and draws influences from jungle, dancehall, and hip hop. The style is typified by rapid, syncopated breakbeats, generally around 140 beats per minute, and often features an aggressive or jagged electronic sound. Emceeing is a significant element of the style, and lyrics often revolve around gritty depictions of urban life.
