limited sound palate, killer headbanging riffs...
His stuff over the last couple of years has been pretty piss poor. But he used to make some really good tracks pre-circa 2006. Raindance, in particular, really stands out in my mind.
I think in a way its interesting to witness the very divergent paths that a lot of the original grime producers/DJs have taken.
To generalise somewhat you've got those that have gone down an aggy wobble dubstep path - Plastician, MRK1, Scandalous Unlimited (saw him play on sat night and it was pretty horrific). Some have got on the funky - Marcus Nasty, Geeneus. Some on bassline - Dexplicit, Cameo (I'm assuming Cameo's still playing mainly bassline on 1Xtra?)
In fact, it'd be interesting to try and do a 'Where are they now? Grime Special'
