For a white kid from the UK this guy has a serious amount of soul and flow. Handbook can chop up samples and make beats with the best of them and has drawn the obvious comparison of J Dilla. The guy's been releasing consistently amazing beatstrumentals for a while now and he's only getting better. This guy is one for the future. Obviously a lot of different rappers are jumpin all over his beats but until someone whose ability is on the same level as Handbook's takes a shot, I think his beats are better off uninhibited and on their own. A couple of my favourites are here, but honestly, just go to his soundcloud where you can listen to or download them all for free.
