Well written article that doesn't say much:
Hey guys, there is something new and cool to exploit and some people are making some money somewhere somehow. It can be tricky, but with some luck, you can make money too!
There are a lot of assumptions and suppositions. The key point to me is that EDM is crossing into the mainstream (which we knew) and is now being viewed as exploitable by investors (which is new).
The last time this happened was alternative rock in the 90s, IIRC. I, for one, hope that EDM is truly embraced by the mainstream. Of course, if it is, then what will the underground move onto?
