On this topic, for those unaware, there are actually quite a few bands of this emerging micro-genre, each executing the concept to varying degrees of success. The earliest example
to my knowledge would be
Cobalt with their release "Gin" (I don't know if their earlier albums fall into this category, haven't listened.)
Wayfarer is another one, featuring the drummer from Blood Incantation, though aside from the occasional vaguely Ennio Morricone sounding riff they pull mostly from bands like Agalloch, so mileage may vary.
Vital Spirit does the style extremely well, and then
Dark Watcher is kind of middling. All are worth checking out if you find the style intriguing.
