N-Dubz madman Dappy wastes no time putting his multi-plat-selling self out there having just announced the group's departure from Def Jam. Tearing through YC's Sonny Digital produced 'Racks', Dapz underlines in no uncertain terms that he is in the top tier of UK rappers, doing everything right and effortlessly setting the pace for what we hope the future of UK hip-hop will sound like. If he's not this country's Dwayne Michael Carter Jr, we don't know who is.
