Most of dubstep is still dark it's just that the biggest labels stray away from it. However Disciple is signing more underground artists. It might not be super dark but Truth's Wilderness of Mirrors album is probably the darkest thing i've heard from a "major" dubstep label in a while. PhaseOne's last EP was a pretty good effort too.

Dark and wavy, just how dubstep should be
