Or, you can choose not to take it absolutely literally, and just make sure that are the proud owner of all the releases I mentioned, and, if you choose to, some of the others mentioned in this this thread. Not "Lugburz", though, as it's barely above average, and sounds somewhat unfinished. "Dol Guldur" is quite excellent, though.
Dol Guldor is an excellent release, my favorite by the band, but Lugburz is hardly "barely above average." It's significantly better than any Mayhem release, which I recommend listening to for historical purposes only. I'd stay away from "At the Heart of Winter" as well. Shitty abyss pruduction, overlong songs, and it's not really black metal. It's more of a anthemic heavy metal record made by a Norwegian BM band. On the plus side, it's not nearly as bad as "Sons of Northern Darkness."
I'm too lazy to type up a list of 50 albums, if you want that, you can search my posts because I recall doing so in the past. I'll just toss out a few.
Avzhia - Dark Emperors
Mutiilation - Remains of a Ruined, Dead, Cursed Soul
Nox Intempesta - Damnanus - Dominum
Manes - Under Ein Blodraud Maane
Epheles - L'ombre de la Croix
Varathron/Necromantia - Black Arts Lead to Everlasting Sins
Sorcier des Glaces - Snowland
Mjölnir (Ger) - Hinweg über die Tore der Zeit
I second Burzum, early Immortal, Darkthrone(UaFM, TH), Fullmoon, most Graveland(TS in particular), Aeternus, Sort Vokter, Galgeras, Enslaved, Gorgoroth, and some more of the ones I've seen mentioned.
If you find a distro with copies of the Epheles, Nox Intempesta, or Avzhia, get in touch.
