Steve said that DSO wasn't one of them. I think he is wrong, but couldn't quite come up with my own list. Let's say within the last ten years.
I would say Krallice is probably up there for me. But I can't think of any mid-2000 albums that grabbed me. I never loved Blut Aus Nord, Taake or Lunar Aurora. Watain, Absu, Wolves in the Throne Room, and Shining might be on my list or Peste Noire if they hadn't gone so hokey. Cobalt maybe if they actually count as black metal. Xasthur and Leviathan were always too fuzzy for me, besides here and there out of Leviathan's catalog.
1 Deathspell Omega
2 Wolves in the Throne Room
3 Krallice
4 Panopticon
5 Watain
Mine is obviously US heavy, but there has to be some bands I'm missing. But I really don't see anybody being better than DsO.
