"36 Ghosts IV" has never been played live.
===Analysis===
The song features the recurring sound simalar too that of a insect type creature, possibly that of a cockroach. Considering that the cockroach would be the last surviving creature of a nuclear apocalypse the song fits well with the post apocalyptic dystopia theme explored in Year Zero

While '''"36 Ghosts IV"''' is not the greatest example of this, it should be noted that the much artwork embedded into the files of the official download of ''[[Ghosts I–IV]]'' from nin.com are not just croppings of the photographs in the PDF.
