check out 'Einblick In Den Qualenfall' from Verdunkeln. awesome stuff, i'm sure you'll like it!
At last, some people in my camp.
However, I have to disagree with your assessment of ITNE's production. I don't find it at all gritty; instead I find it perfect in terms of acoustics and overall atmosphere it creates, as if it were recorded in the great hall of a stone castle (that's the image I get when listening to it).
I keep switching back and forth with Peste Noire. At one moment I like them and but than I dont. I really dont know why people rave about about Alcest so much.
