Almost 20 years on from its first beginnings, grime dominates the music charts and awards ceremonies, and even influences politics. Here, rapper Rodney P examines how grime rose from the council estates of east London to become the most important British musical movement since punk. He discovers that its success rests upon the original styles and contributions of previous generations of artists and learns that grime can only be truly understood when viewed as part of a broader social narrative and ever-evolving musical culture that goes back to the 1980s.
