'''''Year Zero''''' (also known as '''''[[Halo numbers|Halo 24]]''''' or ''Year Zero: Zero-Gen-Ten'' in Japan) is the sixth studio album by [[Nine Inch Nails]], released on April 13, 2007 in the UK and Europe, and April 17, 2007 worldwide, by [[Interscope Records]]. It was produced by [[Nine Inch Nails]] frontman [[Trent Reznor]] in collaboration with [[Alan Moulder]] and engineer [[Atticus Ross]], both of whom worked in a similar capacity on Nine Inch Nails' previous major studio release, ''[[With Teeth (halo)|With Teeth]].'' Mastering was done by Brian "Big Bass" Gardner.
In a 2005 interview with [http://en.wikipedia.org/wiki/Kerrang%21 Kerrang!], Reznor expressed his intentions to write material for a new release during the ''With Teeth'' tour, and it was confirmed that he was working on it by September 2006. ''Year Zero'' began its mixing stage in January of 2007, and Reznor stated on his blog on [[The Spiral]] blog that the album was finished as of February 5, 2007. The album marks a new style of lyric writing for Reznor:
'' “...for the first time in my life, I wanted to break away from the idea of opening up my journal and transferring that into song lyrics. And I really thought about what was at the forefront of my concern, and, at the state I'm at right now, at the age I'm at, just the state of being an American citizen, a lot of concern I have about the direction the country's headed in, and uh, kind of the erosion of freedoms that seems like we're experiencing, and the way we treat the world and our own citizens felt like something I needed to comment on.” '' [http://www.youtube.com/watch?v=xr8FXnur5Z4]
