Unpopular opinion: I don't really care about phones at concerts
Just wanted to say this because I saw a video of Harry Styles telling everyone to put their phones away. Mind you, his "tour" is technically just a residential at MSG and was extremely expensive.
Personally, I think, by having phones, it makes the concert more accessible to people who couldn't go. It shares the art with others. And if you're going to be paying hundreds of dollars in tickets, you should be able to film your experience.
Imo, as long as it's not being harmful for others at the concert, I think people should be allowed to film. It's a concert, not theatre
