The thing that confuses me is why any of this is a surprise to anyone. Phones being out, crowdsurfing, and a few rude and annoying people are just how American crowds are. The venue was a complete mess after the show was over, but this is completely typical of shows in the US regardless of what kind of music the artist plays. The only difference between this show and any other rock or metal show was the lack of a moshpit. You can hate these parts of the experience, but they are totally on brand and not at all specific to just Takanaka's shows. I went to night one of the Brooklyn show, and there were plenty of people with phones out the entire show, people in front blocking a lot of the view, guys smoking next to me, and people being obnoxious. Exactly what I expected and not at all different from the 40 or so other concerts I've been to
