This is a big problem with a lot of shows. I'm fine with you taking a few pictures, but to be on your phone or whatever all the time, why even bother going? It should be about the music. Which is why when I saw Jeff Mangum it was one of the best experiences I've ever had. This is because all tech was prohibited during his set, and if you attempted to take a picture security could (and did to some people) either move you to the back or ask you to leave. If you're at a show, it should be about the music. Period.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.
