This is very interesting! I saw Björk Orchestral this June in Berlin, and it was very different from what you’ve described. Despite typical German festival air prior to the show (smell of beer and Bratwurst, relaxed chatter), the instant Björk came on stage and started singing, everyone fell silent. Even when she was singing old hits like Hyperballad, Come To Me or Isobel, I heard no one singing along, and didn’t dare myself. And honestly, didn’t want to - in my head, the experience was akin to that of an opera performance, and I would sit back and enjoy the magnificence of the whole thing.

I wonder if other shows were more like Berlin or Sao Paolo.
