To me this is DSBM at it's best. calming, emotion filled riffs, vocals are a perfect blend between heart wrenching and eerie, and last but not least, the ATMOSPHERE. One of my absolute favorites for this sub genre The Laughing Stock
For those of use whose attention span isn't what it was for ambient and who need something more narrative than noise, there is the sub-genre of atmospheric black metal that I'm inclined to call "monolithic". Paysage d'Hiver might be the archetypal example. But if you just want to be consumed by a relentless wall of beautiful air pressure, this is ideal. Luke
