just saw Dimmu Borgir live, and I didn't like most of their songs, but there were 2 songs that were really really kickass sounding. I have no idea what they were, but I'm assuming it was their older stuff since I'd assume they'd be playing mostly their newer stuff and I've heard people say their old stuff is good. So which albums of theirs should I check out?
In terms of the quality of their riffs/melodies, the '96-'99 period (
Stormblast,
Enthrone Darkness Triumphant,
Spiritual Black Dimensions) is their best. Lots of memorable, keyboard-heavy songs. I'd recommend starting with EDT.
The early two albums (
For All Tid and
Stormblast) are a big step down in recording quality from everything else, which may or may not appeal to you depending on your tastes. They did a re-recording of
Stormblast, though, so you can hear that one in their modern sound - though it's not as subtle and atmospheric as the original.
Ever since
Puritanical Euphoric Misanthropia, their sound has gotten more and more mainstream, and the songwriting more generic. PEM has a few great songs, but overall is pretty patchy compared to the earlier albums.
Death Cult Armageddon is okay, but not really worth it unless you have a serious hard-on for orchestral metal.
In Sorte Diaboli is by far their worst album, and I cannot recommend it to you on any grounds whatsoever.
Hope that helps you in your decision.
