Anyway, the first artist I heard and associated with Dubstep was Figure on Soundcloud (Beetle Juice Beetle Juice and other horror movie samples used) Think it was 2010 - Actually quite liked it and showed it to a friend. He couldn't get enough of it haha. My interest faded rather quickly...
I have no way of knowing.
I started listening to SubFM internet radio back around 2007 and there was some good stuff there.
Also I'd download awesome full MP3 sets from http://www.garagepressure.com/radio.html
I think I learned dubstep from Destroyer.net, a drum n bass forum site and internet radio station.
It seemed really cutting edge then, and most of it wasn't brostep. Then later on, I started listening to internet radio station Dubstep.FM.
I got a steady stream dose of dubstep from those internet radio stations.
You can still find some of that stuff on http://shoutcast.com Just search for dubstep.
I for some reason found out a youtube channel called SaladUK and the first video i watched was The Lonely Island's "Im on a boat", the dubba jonny remix, i was really amazed by it, and the i listened to more tracks of his and also some bar 9 tracks, i think i had a great start because i still love both producers a lot nowadays.
Think I wiki'd it when I heard about it specifically so that would have been Skream, since he was on teh wiki page. I remember listening to sub.fm at work through itunes for quite awhile around 2007/8 as well. I guess I was late to the party and like many others I got into the brostep type stuff for a good while too.
I bought this at the time to see what all the fuss was about. Thought it was OK, a welcome move away from grime and similarities with the broken beat scene that was going around London for a few years. At the same time, it was fairly obvious they'd found a world music sample CD down the back of the sofa and decided to use it extensively. Need to play it later today though
