im a huge fan of babylon system, jakes, rusko, etc...and this is some quality DUB. tight shit homie keep it up. only thing i can think of immediatley is a deeper secondary beat backing it, but thats more personal taste of how i like my dub.
dubstep has made it stateside!!! I live in the second city of dubstep (bristol, in england for any of you who don't know) and the scene is pumping. Try plastician, skream, benga, n-type, caspa, rusko, chef, j5ive. There's another good podcast, it's called rinse fm.
