Couldn't agree more with the no phone sentiment. I just saw James Blake this week and there was a sea of little screens floating above the crowd the entire show, filming the stage. Definitely ruins the moment as far as I'm concerned.

But there are some people who are doing interesting things surrounding this issue. I recently saw Dan Deacon in concert. He has an app that you can download which turns your phone into a light show that is coordinated with the music. Everyone's phone glows and pulses in unison. It is emergent and beautiful.

If anyone saw Aziz Ansari's standup special, he does this funny thing at the beginning where he reminds the audience to keep their cell phones off at all times. He then goes on to say that he knows people won't do that because they HAVE to take a photo. So what he does is say Ok, everyone get out your phones right now, it's camera time. Then he proceeds to pose in these funny ways while the entire audience shoots him. It's quite funny and seems to be effective too.

And for anyone following him on instagram. He just posted this image... "Damn. Remember when people would just watch the Coachella webcast without having to film it on their stupid phones??"
