Here's a great article by Dan Hancox i came across on the Red Bull Music Academy blog about grime events in London not being permitted:
"From rooftops to chart-topping, the music’s never been more popular, nor harder to hear in public. Dan Hancox on the Met’s attempt to banish grime from the capital’s clubs, in today's issue of Daily Note...
Grime has always been the most local, the most London of genres. In 2003, in a pirate radio studio on a high-rise rooftop in east London, Dizzee Rascal and Crazy Titch battled each other on the mic, and the ferocity of their egos resulted in them squaring up to each other in that crowded box-room. They were prised apart by Wiley, as Tinchy Stryder, D Double E, and about a dozen other phenomenal talents stood centimetres away. That’s how intimate the genre that now tops the charts was at the beginning; so much flair confined into the tiniest of spaces. Ruff Sqwad’s MC Fuda Guy recently told me just how small a world it was in the early years: “To go to another youth club in another area, and for people to know about Ruff Sqwad there was mad. Then for people to actually hear us in other areas outside London, like up North, was just insane – we were like, ‘How did you even hear our music?!’”
