In 2010, I flew to Vancouver to see Watain, a black metal band from Sweden. It is one of the creepiest concerts I’ve attended to date. They impaled pigs’ heads on flaming upside down crosses, and during their set, the lead singer Erik hovered back and forth on stage as if he was possessed. About half the people that showed up left because of the smell of rotting flesh and chloroform. I luckily avoided the pig’s blood that was thrown onto the crowd, and the end of a mic stand that was being jerked in my direction for taking photos.
Check out Watain’s music. Not for the faint of heart.
