A collaborative split recording between the legendary Germany composer Hermann Kopp and the Roman act Bathory Legion. Bathory Legion, who came up with the title "Das Unheimliche" (uncanny or eerie), holds this concept to be the natural evolution, the coagulation, of the previous album "Drepe", with its esoteric and sinister meaning overcoming the psychological one. The Roman artist imagined a modified tetrahedron, a "terrible jewel", as an alchemical symbol fading into beauty. Bathory Legion's opening track, "Lahko" (sect or cult) begins with a voice captured from the Russian radio UVB-76, evolving into a rhythmic avant-garde and experimental ambient adventure. Hermann Kopp, known for his soundtracks to Jörg Buttgereit's Nekromantik and Der Todesking in the '80s, bases his uncanny track "Scapinelli" the 1913 film The Student Of Prague, in which the titular demonic figure makes a young student sell his soul, takes away his reflection in the mirror, and creates a disturbing doppelganger. His second track, "GAS n.71", was part of a series of recordings realized in 2017. The recording was covered and remixed by Bathory Legion as the second track of the release with an intense pipe organ and drum sound. For the cover art, Bathory Legion photographed a fairly old bottle in a house of the Apuan Alps, and this fact is full of meaning - will remain secret - then creating a digital painting of it. 28 minutes.
