Metastatic Resonance by Lustmord - similar artists / titles?

Ever since I've heard Metastatic Resonance by Lustmord (i.e., since The Place Where The Black Stars Hang was released back in 1994), this has become a true milestone in dark ambient for me, an ultimate and outstanding experience that has never been reached again, or at least I've never been able to find anything that comes really close to it.

There are lots of other artists / works that I do appreciate very much, but actually none of them matches the intense and dark atmospheric depth found in Metastatic Resonance. Other albums by Lustmord (Heresy, The Monstrous Soul, [ B E Y O N D ]; Stalker in collaboration with Robert Rich) tend to go in that direction; also various otherwise great works by Steve Roach (Mystic Chords & Sacred Spaces, Afterlight, Dynamic Stillness and others), yet these do not have the final pinch of "darkness". (However, basically they come closest to what I am looking for - vast atmospheric soundscapes)

Recommendations, anyone? :)

DeepRV: yes, thank you very much. Phase V actually comes close to what I am looking for, especially the second half (very vast, dense atmosphere) - deeply layered sounds merging into one almost static and dark wall of sound..
