Zomby is doing some pretty interesting things now. He released 'Spliff Dub' on Hyperdub a while ago and has kind of reset the balance within dubstep - with producers finally taking a few risks. Along with Oneman he's probably the most interesting producer at the moment.
I heard 'Strange Fruit' a while ago and it's stuck in my head. It is the best dubstep tune this year. Easily. Apparently he only gets photographed wearing skulls or a gold mask. I couldn't find any of those pics so I had to use a picture of Billie Holiday style strange fruit.
