Urban review: N-Dubz, Uncle B

Camden teenagers Dappy, Tulisa and Faze are noted for their work ethic - tireless school tours have garnered them a significant fanbase - and their penchant for hard graft is evident in their music, too. Their talent is raw, to say the least, and you feel they are not yet sure how to use their strengths; the effort put into Uncle B's 17 tracks is palpable. Still, at a time when so many teenage pop stars seem to be old before their time, it is refreshing to hear an act with such messy youthfulness. Inevitably, this results in moments of gaucheness - Dappy's rapping can be ham-fisted - but there is a certain vitality here that marks them out. On N-Dubz Vs NAA, an argument between Dappy and Faze escalates over dramatic strings and echoing beats, while Tulisa attempts to intervene with keening vocals; Don't Get Nine features Dappy and Tulisa trading rat-a-tat back-and-forth barbs. Both seem more like stage productions than tracks, and are much more compelling than some of the more standard cuts.
