Biohazard guitarist Billy Bio had a pretty bad time during the band’s recent show at O2 Academy Islington. According to Bio in a Tweet, he was dropped on his head by security at the show and doesn’t remember the entirety of the night. Here’s hoping Bio got some medical attention for the injury, because memory loss after getting dropped on your head probably isn’t good.

“Thank you London for an amazing show! Had an incredible time until security dropped me on my head!” wrote Bio. “Thank you @o2acadislington, I have no memory of tonight, just this video. Hahaha”
