Roll Deep, Rules and Regulations

The first of two planned albums this year by the revived East End crew, Rules and Regulations arrives with their leading light Wiley publicly contemplating retirement and grime's bleeding-edge kudos seeping off into dubstep. For all that, it's a sparky, if ramshackle, mixtape, with the ragga-tinged and hilarious 'Weed Man' rubbing up against the earnest 'Racist People'. Those who fret about grime's attendant violence will be heartened by the witheringly anti-gun 'Badman', but Roll Deep's strength is in the dizzying variety and remorseless assault of the 13-strong group's spitfire verses.
