Phlebotomized- Immense Intense Suspense
Hail- Inheritance of Evilness (if its really limited to 666 copies)
Creepmime- Shadows
I have all of these too. Awesome albums. I have a bunch of modern Black Metal albums that are limited to scare amounts of copies, but I won't really consider them rare for a few years yet. I guess Dark Tribe's
Geboren an den Ufern des Wahnsinns (Self-released by the band, limited to 500 copies) is the rarest out of that lot.
This is probably the rarest item in my collection:
Moonblood - Blut & Krieg (Original Cassette, limited to 666 hand-numbered copies #579/666)
Anyway, as far as I'm aware, these are all pretty rare.
