*I'm going to NSFW all youtube links to save page space*I like them a lot. Here's a youtube of the full album if anybody wants:
Deafheaven - Roads To JudahBack on the subject of classics (I'm not going to be strict with a timeline or waves, just what I consider "classics" of the genre)
The Darkthrone album I would have picked is already posted below by fungalattack
Ulver - Bergtatt (One of my all time favourite albums of any genre)
Carpathian Forest - Through Chasm, Caves and Titan Woods (Couldn't find a full album link so here's just song 1)
Gorgoroth - Ad Majorem Sathanas Gloriam (A lot of people would pick a different album by them - maybe Incipit Satan or Under the Sign of Hell, but whatever. This is probably my favourite Gorgoroth album.)
Emperor - In the Nightside EclipseBurzum - Hvis Lyset Tar Oss (or Filosofem)
Enslaved - FrostDissection - Storm of the Light´s BaneDimmu Borgir - For All TidImmortal - Pure HolocaustMayhem - De Mysteriis Dom SathanasSatyricon - Dark Medievil Times (or Nemesis Divina) (Couldn't find a full album link so here's just song 1)
1349 - 1349Bathory - BathoryAbigor - Verwüstung – Invoke the Dark Age (Couldn't find a full album link so here's just song 1)
Beherit - Drawing Down the MoonOphthalamia - A Journey in Darkness (or Via Dolorosa) (Couldn't find a full album link so here's just song 1)
I could go on for a really long time, but I'll leave it at this for now...
