Yesterday I went with Yul to a concert of the Doom band Sunn 0))).
It was really weird and extremly loud, It was more feeling than listening to music. When you closed your eyes it seemed like the sound came out of your brain. Also it was more like a celebration than a real concert. They summoned a tree :D
For all that don't know Sunn 0))) here's a live video. But I don't think it's music you can listen to, because the atmosphere and the pressure of the sound doesn't come out.
Hell, it was the best weird concert I've ever been to.
