Some D&B artists that are making Dubstep:
Black Sun Empire
Ed Rush & Optical
Twisted Individual? I think.
12th Planet (Infiltrata in D&B)
BAR 9? These guys sound like they produced D&B, but I'm not sure about this.
Crissy Criss has a new Dubstep single out - "Soap Dodger" / "Don't Mess About"
black sun empire's dubstep project
Tech Itch has been running a solid string of releases with a dubstep label called ascension (i think this is his label - judging by the release record).
Haven't heard any of it to be honest, but i would like to (unless someone would PM it to me)
Anyway, here is the discogs link.
