I've listened to the whole song several times now despite its duration. Atilla Csihar's vocals are probably my favourite part, even if they are a theoretical disaster. It reminds me of some sort of Christian mystic/Gnostic ritual. Anyway, the Internet seems to be of little help on this one. Are there any real lyrics? I do believe I heard "It calls" at one point but I could be mistaken. Can you make out anything else?
