It probably wouldn’t fit your thrash and death metal tastes, but sludge metal and doom metal are a lot less likely to have screaming or annoying vocals in them. I personally really don’t like screaming even though I like metal, haha.
Otherwise, acoustic metal is where you want to land. It can be hard to find in my experience, though.
The latest Tool album.
I can’t even remember the name, but it felt like a lot of noise from an alley full of garbage cans. I don’t know if I finished listening to it.
