@bloodyblade i noticed that too but this song comes on right before der rutenmarsch and i got this quote from wikipedia [[[Note: According to Belphegor's official website, "The Sukkubus Lustrate" & "Der Rutenmarsch" are actually one track.]]]
This is a great example of a black/blackened death metal band using a modern, cleaner production in a good way, to enhance the atmosphere rather than strip it away.
