You know, for countries any band visits all the freaking time, it is not a surprise the crowd is not that energetic. They’ve seen them live a bunch of times so it is understandable.
As for flashmobs and crowd interactions with the band with phones/led lights, it happnes almost everywhere, the photos and videos just don’t always capture it.
Plus, crowds vary from country to country. You have the crazy ones from Brazil, Italy and Russia, the typical always-hyped-up Germans etc. They’re all having fun in their own ways.
It annoys me as well when people just shoot all the freaking time but you can’t really tell them how to enjoy the show. That’s their way of having fun in the end.
