The story of the opening track is very interesting:
The opening track "Silvester Anfang" was provided to the band by German electronic music composer Conrad Schnitzler, after Euronymous found Schnitzler's home address and sat outside his house until he was eventually invited in.[4] Euronymous then asked Schnitzler to compose an intro for the album; rather than record a new composition Schnitzler gave Euronymous a random piece from his archives, which would later become known as "Silvester Anfang".
