For us who can't understand French here's the translation
Hey Stephanie,
I understand your frustration but this guy is a pro so he did his job. This is the difference between the amateur who makes his photos are disturbing (though not always) and the neighbors looking pro LA Photo therefore ignores his entourage. The picture at the bottom of the room is less impact photography and I know a little about ..
Finally, I think we should be tolerant if it should turn those who hide the view standing on the shoulders of a friend, who spend their time chattering rather than listening to the concert, those that challenge the world to go seek a foam, all these people trying to make video / photo with their phones, great for hiding the small, etc. ... those pogottent
Anyway, I'm exaggerating but it is all the ambience of a concert with the pros and cons.
See you at the next concert NMA
