YES. I've only spun a couple of sets at very small venues, but nothing made me happier than to look out and see as many people dancing as possible. It's the most sincere form of flattery you can show a DJ. If a DJ sees you watching them, what do you want them to do? A trick? They're just twisting nobs and crossing faders, like every other DJ. Most of the big acts are just pretending anyway (that's Justice... unplugged), they've got a pre-recorded set. Mixing live (note: mixing live well) is hard, especially under that kind of pressure. Maybe one problem is that big shows are, like... things, now, you know? People flock to "the scene". Admittedly, I only really dance when other people are, and it usually takes a couple of beers beforehand. I'm nowhere near immune to social pressures. Related problem: Recently went to a little show (no one you know DJ'd, trust me) with a friend of mine from my first couple of college years. They were on their social media almost the entire time, posting to instagram, facebook, twitter, face-timing their S.O., etc. Only maybe 35% of the time did they actually focus on the moment. Edit: I would like to add that it can be a little different when there are actual turntables involved. I was born into the generation that typically employs Ableton, Traktor, or other digital means of mixing tracks together, and unless you're on stage or behind the DJ, there's not really anything to see. Watching someone work a pair of turntables can be a little more interesting, especially if they've got "dat scratch" goin' on. Anyway, if you're in front of the DJ, and they're elevated up above the audience, there's nothing to see... so dance!Is it time we took the focus off the DJ?
