EDM is not going anywhere. It will continue to progress and encompass a greater part of the music landscape, but the DJ's place, in a live setting, is going to have to change.
The current charade cannot endure... You know, the DJ presses a button and jumps around like a fucking idiot while the molly-fueled crowd tries to catch a glimpse of him bobbing up and down... In 20 years we will look back on this and laugh our asses off.
I think that slowly, but surely people are becoming more aware of the absurdity in this ritual... If I am right, and people are actually wising up, then what will happen to LIVE EDM?
In my opinion, the logical path that most acts will have to take in order to stay ahead of the curve, is towards increasing anonymity, surrounding the DJ persona (Like Deadmau5 - who is a decade ahead of everyone else). The best solution to the awkwardness is to try and disguise the adoration of a person who does little more than stand behind a table and pretend to make decisions (like so many of my past bosses). The way to do this might very well be through costumes, helmets, or elaborate light shows that dwarf the man/woman standing in the booth. But something about the human presence, even if veiled, seems impossible in the future ....
Maybe DJ's will have a whole rig that corresponds to their most recently compiled 2 hour set and they will just send that rig, "unmanned", to various venues throughout the world? A stagehand will press play and off it will go. In many ways like what Deadmau5 or Amon Tobin do now, but in this case the DJ will be entirely removed from the picture. He will build the playlist, construct the various layers of sounds, design the visual theme, etc, but he will not stand on the stage fist pumping.... Hmmm... Am I on to something here?
Final Note: Yes, I know, not all DJs are just button pushers, but to me, it sure seems like most of them are. At least the ones who are selling out large scale venues.
