In short, I'm looking for albums similar to Spectral Voice's full length.

I came across Spectral Voice a while ago and initially found them cool, but then boring and derivative. Acting on my first impressions I recommended them to a friend who sort of rediscovered them. I gave them another try, really taking my time, and their sound has really taken off with me. It's stripped down, rather simple, and maybe even a bit formulaic - but it's sincere and just such a pure distillation of an idea.

If you could point me in the direction of similar and equally good, if not better, material I'd really appreciate it. I grabbed Incantation, Blood Incantation, Father Befouled, and Dead Congregation.

Antediluvian
Portal
Temple Nightside
Mitochondrion
Adversarial
Abyssal
Vassafor
Paroxsihzem
Desolate Shrine

disembowelment is prob the biggest influence on spectral voice
