What about the translation to Darkthrone's Over Fjell og Gjennom Torner?
Also "Slottet i det fjerne" has the line 'dark ones who worship the sun' - a bit less direct than Oven Fjell by Fenriz:
"den norrene rase ma slagt den andre
nar blammen dunker for tunkt na pa dor"
'The northern race must kill the other
when African-Americans knock hard at the door'
or Flittermice lyrics by Varg:
"A fare to raise the flag of satan, and disseminate the races
to build a hall of battle, and live in eternal strife'
all this on an album labeled Norwegian Aryan Black Metal. Not to mention all the pagan themes barely hidden by Varg underneath a satanic veil when writing for Darkthrone. Can't really say its all indicative of any sort of NS ideology... more of a gut reaction to the cosmopolitan nature of the city (Varg and Fenriz had been living in Oslo around these times. Both Over Fjell og Gjennon Torner and Slottet i det Fjerne (indeed the whole album) give the listener a powerful sense of terrible beasts lurking outside the gates of civilization... and terrible beasts lurking within the hearts of civilized men whose lives have become too soft and easy (dark sun worshippers). Both songs have characters lurking in caves and swamps, clawing through thorns and over mountains. It reminds me of a line from Apocolypse Now, "Every day that I sit in this hotel room I get weaker, and each day that Charlie squats out in the bush he gets stronger." It is worth noting that the members of Darkthrone retreated to the forest for a while during and after TH was recorded.
Edit: I did not know the N-word had a filter. Obviously Fenriz has never written any lyrics about African-Americans.
