Last year was the year grime failed to break big, and nobody failed to break big quite like Wiley. His excellent solo debut was festooned with praise - but the ambitious founder of the sprawling Roll Deep Crew, and one-time mentor to Dizzee Rascal, isn't in it for good reviews alone.

Hence In at the Deep End, a record twisted in knots by the need to succeed. Bids for airplay come no more blatant than The Avenue, which doesn't so much sample the Maisonettes' 1982 soul hit Heartache Avenue as does the bare minimum required to qualify it as a different record.

Although their rhymes are reliably enthralling, all the R&B hooks and sub-Kanye West accelerated vocals sell the crew's production talents embarrassingly short. By contrast, grimier tracks such as When I'm 'Ere blaze with ingenuity and unforced vitality. In at the Deep End is half a great record; if it didn't sound like it had been recorded with one eye on the bank statement, then it might be a whole one.
