}}'''"Vessel"''' is the fifth track on the 2007 release ''[[Year Zero]].''
Musically, the song consists of heavily distorted drums, a wall of synthesized sound that hits in a percussive way locking up with the drums, Reznor's vocals not as obscured as on other songs, and ending improvization using a set batch of sounds reminescent of a traditional guitar solo. However, this section is not performed on guitar, but was the result of estensive computer editing of programmed parts that allude to a traditional guitar solo.
===Theories===
There is a theory that "Vessel" is about [[John of Boston]]. In the transcript of his discussion with the facility member he mentions that he is a vessel for the truth. Another theory is that the song is about pills given to US soldiers to counteract the effects of [[Parepin]] or [[Opal]]. ("When I put you inside of me, none of that matters anymore" and "I am turning into God" suggests this.)
