Yeah, I'm with FarleyCZ, I don't buy it. It MOSTLY takes luck, or rather "being in the right place at the right time." A lot of famous artists (I'm talking EDM here) were producing well before the EDM scene really took off (especially in the US).
Take deadmau5 for example. He was producing on his own in his parents' house, started working at a studio learning the ins and outs of hardware production, and was a bit of raver. He knew Steve Duda and one day they were messing around and saw that mp3.com (or was it beatport?) had some EDM on there. Up to that point, he hadn't really produced a lot of 4 on the floor type beats, but when he heard what was top-ranked on the site, he knew he could do better. So him and Steve (together: BSOD) produced a "joke" track called "this is the hook" (

If you listen to deadmau5 or follow him closely, you know that he dabbles in a lot of non-EDM electronic music. In fact, you could say that truth be told, he "dabbles" in EDM, cuz that's the moneymaker of his time. I'm not implying that he's a "sellout" or anything, just saying that it took the mix of his talent, background, connections and being at the right place at the right time for him to become a massive global phenomenon.
