I try hard not to take too many scenery photos...because honestly I can get better photos of the place than the professionals. I usually take photos and then delete the after, it's an itch I have to scratch.
Also this is a big pet peeve of mine:
Supposedly you are there to listen to the music, to have a unique experience, right? Or are you there to show off to everyone that your were at this cool concert? I like taking photos at concerts, but minimally so, not so much that interferes with the show. I took a photo of the palm trees while listening to Leonard Cohen - because it captured the feeling of the moment - the picture came out kind of crappy but I love it because it function as a trigger to my memory.
So yeah the inner photographer in all of us needs to take it down a notch, be less trigger happy.
