Don't bother with Samael's first two albums. Extremely mediocre black metal. The post-black metal stuff is the most interesting, and Passage is the best example of that. It would be the popular critical favorite as well, if that helps.

On the contrary, early Samael is extremely overlooked 2nd-wave Swiss BM. Even with the inclusion of slight operatic influence (Ceremony Of Opposites), their early stuff, even before Passage is worthy of multiple listens.

Passage is pretty good, though, yes. I even like 2-3 songs off Eternal, such as Supra Karma, The Cross, and I.

Dimmu Borgir - For All Tid
Dimmu Borgir - Stormblåst
Death - Individual Thought Patterns

I find the new Kamelot highly mediocre I can't believe they made an album as mediocre as that after the amazing "The Black Halo" oh well modern Black Metal lately has been making some amazing albums in the 00s.

I agree it sounds like they just used a bunch of left over tracks from Black Halo that didn't make the cut.

I now need to complete my Death collection by getting Human. Also need to find a few Dismember albums.
