Underground Dubstep came from UK 2step, house, beatcore, and other underpaved dub influences. I pray mainstream goes out, I used to be pretty deep in SLE, Relentless Beats, and UK Thursdays out at the School of Rock, but it all gets so old. I like the hyphy loud uppity events, but once they really grind in some dub its like what the hell all my energy just went down. Nothing against the genre, I believe we "Americans" took it too far as a trend. I mean look at LMFAO, stupid ass music, burnt brains from X, and with nothing to contribute. Shuffling? I've seen some crazy ass shufflers spinning fire at the same time and LMFAO wants to talk bout shuffling. I've personally met SKrillex, Datsik, Zomboy, Liquid Stranger, Helicopter Showdown, Nero, Bassnectar, Sluggo, Tranzit, Deadmau5, Daft Punk, Tiesto, etc. list can go on. They have even said times are even gonna change for us, and when we run out of shit to do with our music, or our design, where gonna be scratching our heads or sticking to World, or DnB. True story. I like filth though, you can really mess with the oscillators, parameters, and filters to grind out each beat. I can share some other underground artists, for darkbeat, filth, and other dub. Even now they are starting to mix dub and djent. Crazy.
