So where does (mainly S London) dubstep from the middle of the last decade fit in all this? Sign of the Dub, Loefah, Kode9, Burial, DMZ, Mala, Benga, Skream, etc etc And people (more recent?) like J:Kenzo, or the whole Pinch, Shackleton, Applebim group from Bristol?

Feels like there's this disconnect between what Dubstep used to mean and what it appears to mean now. The same genre name being used for two things that are fairly, if not completely different.
