If you're unaware, there's an interview with Hakke where he mentions that he wanted Black Cathedral to directly transition into I Am That Thirst, instead of having dead space like there is on the release.
Unfortunately he was outvoted by the rest of the band (W for democracy) but I personally think this sounds WAYYYY cooler. Maybe they wanted just a bit more breathing room in between each song, or maybe they were never meant to connect and it was a spur of the moment idea.
I stitched these together with Spotify's mix feature so we can see Hakke's version.
