Nocturno Culto agrees that this is by far the best Darkthrone cover on the album, and basically that's because it doesn't event resemble the original "Slottet I Det Fjerne". Now you can't ask for a better definition of TRUE BLACK METAL than that!
But THIS version is not from "Darkthrone Holy Darkthrone" - it`s from a Gorgoroth album. The Darkthrone cover album contained a weaker version that sounds very similar to this one.
