Grime is a style of music that emerged from Bow, East London, England in the early 2000s, primarily as a development of UK garage, dancehall, and hip hop. Pioneers of the style include Dizzee Rascal, Wiley and Roll Deep. Grime is typified by complex 2-step, 4X4, breakbeats, generally around 140 beats per minute, or sometimes structured around a halftime rhythm, and constructed from different synth, string and electronic sounds. Stylistically, grime draws on many genres including UK Garage, dancehall, hip hop. The lyrics and music combine futuristic electronic elements and dark, guttural bass lines.
