The band had this to say about the track: "A new dawn of creation begins with 'Pyramidal Existintualism'. Upside down flying black pyramids are shifting, dark-to-light and back again. Many names, but just one and the same, nature's harmonizing light! Inverted circles and inverted skies, parasitis, embryo extraction, and the mind-altering fungal birth begins! Now that the light starts to fade, and the darkness looms once again, so the hand of fate takes its toll!!"
Hallucinogenesis was produced, recorded and mixed by Randall Dunn (Sunn O))), Wolves In The Throne Room, Boris) at Seattle's Avast! Recording Company (Earth, High On Fire).
