Pure Holocaust>all
I was gonna answer the post above with a big old SACRILEGE! but yes, this. Immortal haven't done better before or since. The new stuff sounds like dumb arena heavy metal to me. You might like it better than the old stuff (well, Pure Holocaust, and to a lesser extent Diabolical Full Moon Mysticism and Battles in the North), but good black metal it definitely ain't. Shit it ain't Black Metal to begin with.

I suppose I wouldn't really call myself a "fan" of black metal though, since most of the genre-defying stuff is too raw and noisy for me (really the only old BM I can listen to is Emperor and Dissection)
