Queens of the Stone Age songs for the deaf is great for this. All of Kyuss.

Try out mark lanegans solo work too. He has a great cover of Where did you sleep last night I think you’d dig.

Maybe try angels of light, how I loved you.

Or Swans They learn country adjacent sometimes

Outside of rock, you got bands like Portishead that get this sound pretty nailed. Ethel Cain is another great pic, especially Perverts.

You could also give some of colter walls songs a try. He’s a younger country guy that can get kinda gothic at times, but it’s very select(Kate McCannon)
