And I have yet to hear any Christmas metal that’s really brutal. I still like Austrian Death Machines’ “Jingle all the way”. But it certainly isn’t technical brutal death metal. But maybe the thing we need is Revocation: https://revocationband.bandcamp.com/album/the-outer-ones

Not a deep cut or anything. Just good solid cosmic horror.
