I would include the Solstice debut, were it not for those dreadful vocals! Moz Ingram on "New Dark Age" was better, I feel; now Tom Phillips has apparently taken on the vocal duties in a reformed Solstice...
Don't you think Disembowelment belongs? Perhaps not on a trad/epic list, but they don't really fit into the atmo/doom-death category either.
By all means look for all releases by Skepticism- if you like early Shape of Despair, you'll like this band as well.
I could simply never get into Trouble- for that sort of creaky proto-doom stuff I always preferred Pentagram.
