The bass-drum beat is very similar to 'The Great Destroyer' Aeontriad
It should also be noted that all the images of the Presence show that it has four fingers or extensions. Perhaps this is indicating the Presence is dying. Aeontriad
I think part of Ghosts 33 can be heard at around 3:04 (Sounds similar to Ghosts 33 at 0:43). Can anyone confirm this? Doriol
I believe this is a reference to the previous album, Ghosts I-IV. "The Four" might refer to the album and and the fact that they're dying might mean that Trent Reznor is probably done with doing instrumentals, at least for the time being. Ruiner13
