borrowed a drum kit from Old Funeral, the successor band Immortal, and "another musician living nearby". On "Hvis lyset tar oss", he also borrowed Hellhammer's drum kit, the same one Hellhammer used to record "De Mysteriis Dom Sathanas" by Mayhem. He used a Peavey amplifier, but for the recording of "Filosofem", he used the amplifier on his brother's stereo and some old fuzz pedals. For vocals, he would use whatever microphone the sound tech handed him, but during the recording of "Filosofem", he intentionally used the worst mic they had, a headset mic. On the track "Dungeons of Darkness", he used the large gong at Grieghallen for background noise (Euronymous assisted him by beating his fists on it).
