I first listened to this album about a week ago and was not sure quite what to make of it at first.
It's in the general bucket of black metal but farther toward the ambient end of the spectrum than pretty much anything else I have ever heard. Imagine if William Basinski decided he wanted to make a black metal album and you'll have a pretty good idea of what's on the bill here.
Having now listened to it at least three more times since then, I can say that this album is excellent and definitely worth checking out.
