Grime is British music that first emerged from Bow, East London, England in the early 2000s, primarily as a development of UK garage, dancehall, and hip hop. Grime is typified by complex 2-step breakbeats, generally around 140 beats per minute and constructed from "different" sounds.
It is difficult to dance to for anyone over the age of 25 or not under the influence of drugs.
Bill: "Can you dance to them?"
John: "No one can: it is an offshoot of uk garage, dancehall, and brit-beat."
Bill: "Sweet - are they on iTunes?"
