Here are some bands that I find quite interesting:
Paysage D'Hiver
Music of Paysage D'Hiver is hard to describe, it sounds just how brain fog feels like - ver heavy, noisy and while appearing chaotic it really is very well structured at the macro scale. Certainly not a band that you would (or even could!) listen to regurally but it's more like an experience. I'm talking about "Welt aus Eis" but it applies to all of their work more or less.
Путь
Путь (pronounced Poot', "path" in russian) distinguishes itself from the rest by having an EVIL FUCKING SKELETON PLAYING ACCORDION (that can even be heard in the tracks!!) (and it sounds awesome). Mostly themed around winter, cold and death. Cool.
Agalloch
I cannot describe how much I adore this band. It has everything i love: romanticizing nature, neopaganism, poetry and WINTERR. If you like nature walks and black metal/post rock it's a MUST.
