I honestly have no idea if you'd dig this shit. But I really love these bands that basically do surf rock music with a horror twist. I love surf guitar and I love horror and so the shit really hits with me, but may not be up any of your guys' alley. Check it out though. 

This is Messer Chups. They are from Russia and they do have some songs with some pretty crazy vocals, but mostly instrumental. They get into some experimental shit sometimes too, here's one that's pretty out there but is one of my favs. This link is for the full album, but the song I was trying to post is the very first track. Can't seem to find it on it's own. 

Another great band that hasn't been together in a long time is the Ghastly Ones. More on the "fun" side of things but great music: 

Also, I've mentioned before that I'd love if ICP worked with either of those bands. For my own tastes, if ICP could blend their style in with either of these bands and make an album like that, it would be their best.
