My kind of thread, I have nearly all of what is being listed.
Apart from the dubstep, because dubstep is shit. Invented in Croyden which is right near me and one of the scrattiest Chav ridden place in Greater London, every tune has the same damn bass line WAGGAWAGWAGWAG and sounds nearly exactly the same.
My addition will The Flashbulb AKA Flexe
His music varies greatly between albums, breakcore, ambient (not my thing), classical. He's one of the few people who can make good chilled breakcore tracks.
An exampleEchoing casull, BT has some very good tracks.
Rose of Jerichoand lol Pendulum... although I have seen them live.
For the best DnB check out anything on the Hospital Records label, my favorite being High Contrast.
bogdan raczynski who's on Aphex Twins label also has a few good tracks.
As far as House goes I heard some decent 16bit Lolita's tunes at this club the other night, checked out a few more of their tracks over the weekend and dig quite a few.
