At a Bullet For My Valentine show in St. Petersburg, Russia, fans lit a fire in the middle of the crowd. And moshed around it.

And there's pictures to prove it!

A pic from St Petersburg 2 days ago. We didn't need to bring pyro for this show as the crowd brought there own! Mental. (P.S this is very dangerous and as awesome as it looks please don't bring flares to shows as it could have ended up pretty bad). .

All joking aside, this is crazy dangerous. Please don't try this at your local show!
