I had this moment with a far less known band, Rosenstolz, in Germany. It was an open-air concert many years ago (the band ceased later on). And even though I was less than 5 meters away from the stage it felt like it was a private gig in a small location. Nobody pushed around. Next to me there was a father with his young daughter. No matter when she wanted to get on his shoulders or off them, it wasn't a problem. It was just like even as everything was sold old months in advance, everybody left each other's personal space. I miss that band.

Just to give you an idea, here's a video of that tour even though it's way more crowded than it was at the concert I visited
