So, Lordi rocked.
No pictures, unfortunately, as the security confiscated my camera half way through the show and wiped the memory card (sorry Aleksei!). But it was a fair cop - my hip-holster is an unorthodox, though very convenient, way to carry a camera as poorly concealable as the Canon A620, and I knew from the start that cameras were not allowed at the event. I was in second row center, with some little Finnish girl in front of me singularly failing to obscure my view of the stage, and did all the headbanging I wanted - so the lack of pics is compensation: were I in the back rows, I couldn't have gotten decent pics at all.
It was a full-length show, no warmup and ended fairly early (because of all the little kids), but otherwise max strength: the only song they didn't do which I would've liked to hear was Supermonstars. And, hey, I got a T-shirt.
