There is certainly a debate as to whether or not cell phones and other camera devices should be welcome at concerts, and I think there's validity to both sides of the matter. On the one hand, performances are often very special occasions which merit something to fondly look back upon. On the other hand, taking these photos and videos distracts those around you, blocks views, and disengages/detaches you from the experience. 

Some artists have taken a firm stance one way or another, and I don't think we should knock them for setting expectations at their shows and sticking to their principles. Some performers, I'm sure, cannot get enough of the camera and will take every opportunity they can to expand their image whilst others just want a good old-fashioned show with an audience that is present in the moment. I'll enjoy a show regardless, but I fall somewhere in the middle. 

As a fan, I feel a little embarrassed when I record a video of a certain song I like, for example. It's like a mix of embarassment and shyness, kind of like pushing up through a crowd that's hestitant to let you by... I tell myself, "be brave Joe."  -LOL 

With my phone in the air, I figure I'm annoying the people behind me as well as giving those on stage a bad view. I know I would rather see people dancing and singing and clapping along instead of posting stuff to their Snapchat. This is not to say you can't do both, though! I think the older the band/artist is, the less they enjoy the new norm, but you just got to get a feel for the vibe of the crowd and not be rude with what you're doing. 

One of the most effective ways to not be disruptive taking photos or videos at concerts is fairly obvious, but so often overlooked. Turn down your phone screen brightness! Let me put that again. When you go to a concert where the lights go down on the crowd, if you feel the need to be on your phone, please turn down your screen brightness. 

That's all for now, thanks!
