Not many 27-year-olds have played Glastonbury four times, but East London's grime-pop king Dizzee will chalk up that achievement this summer. And you couldn't wish for a better festival act than Dizzee. His sets literally bounce with a plethora of hits and summer anthems, gathered from just four albums over ten years. From this summer he'll have a fifth to draw on, including more remarkable collaborations with pop superstars such as Robbie Williams and Calvin Harris. His surprise appearance at Radio 1's Hackney Weekend 2012 (rocking the crowd in his own backyard), followed shortly after by his performance on the Olympic world stage sealed his status as crowd pleaser extraordinaire.
