Seems to be a few different styles that have spawned out of UK Garage. To put it lightly, a "Suburban" 'Fwd' style, as they put it, sometimes known as "Dubstep." Then the "Urban" style which is more MC focused, Aka, Grime, 8bar, or Eski, as Wiley would put it.

I'm not sure if this a "cat" thing, or a collective of "cats," but its good. The "Rick Rubin" track is what I thought the Victor Vaughn stuff was going to sound like. Its a couple of guys from Brooklyn handling the production, and an MC from Baltimore who came up with some Rawkus (records) guys. The first track is kind of electro'y, the second more glitchy.
