For Halloween I'm planning on dressing up like pic related and playing a few extreme metal songs for friends and family on guitar. I'm not sure about the corpse paint, I might just put on a balaclava. I found an app that turns your phone into a sound-activated strobe light so there will be some VFX too.

With or without the lyrics? It's probably too much but whatever.
