Shy FX is my current fave. Yeah, they aren't as hardcore on their albums as they are live but they are one of the few groups taking D&B to the next level.
Kosheen's Hide you and Suicide are also pretty crazy.
Aphrodite's current stuff and of course old Goldie from the Timeless album is hot. Roni Size did some really cool and jazzy stuff that won tons of awards then he fell the fuck off. He even had a couple of good songs with folks like Method Man and others.
TDF you gotta see the way a crowd goes crazy. It's a whole different kinda energy.
