Depends on what you like.

Pic related by Triangulum and Batilda is one of my favorites. They're definitely not the most obscure groups in the world but still underground. It's ultra lo-fi but melody driven

If you want something that's a bit more Pagan or Folk I would recommend Nocturnal Misantropia by Xerion

For more depressive the first thing that comes to mind is this demo by Asymmetry called Ashes Into Wood (It's short, the first track is more of an intro, 2 and 3 are where it picks up)

Finally, if you want to chud out, I recommend Soldau's demo. They have a second demo too that disappeared from the internet but I still have that too
