I've never heard that particular album, but I can tell you that lot of black metal type bands really like the combination of a fuzzbox with a relatively cheap amp. Just plug in a Big Muff or something similar, turn the tone all the way to the 'trebly' side, and let rip with some big fizzing black metal octave chords. This is the 'Dunkelheit' type sound.
If you're talking about the Swedish DM sound though -- and I know that this is mostly common knowledge, so forgive me if you already know this -- just pick up a Boss Heavy Metal or Metal Zone, scoop the mids, and crank the lows and highs, like a normal thrash metal tone except on crack.
Hope this helps
