[3] Klayton worked in earnest with the producer Grant Mohrman (formerly of Leaderdogs for the Blind and Full on the Mouth) on the album, which was scheduled for release in February 2001.

Klayton agreed with various online companies to provide unused songs for download in high quality.

[7] During this time, Klayton kept fans up to date with numerous Celldweller logs through his website and via email and, in 2001, released raw files of the song "Symbiont" to give fans and fellow musicians a chance to remix Celldweller's music.

[10] The unreleased song, "Uncrowned", which is an outtake from the original album and from Wish Upon a Blackstar, was finished by Klayton for this release.

[2] Klayton signed fifteen copies of the deluxe edition CDs which were mailed at random when the pre-orders were shipped.

Every song on Celldweller has been licensed at least once for a movie, video game or another form of media with titles including Doom, Mr. and Mrs. Smith, Supercross, XXX: State of the Union, Spider-Man 2, Constantine, Catwoman, The Punisher, Paycheck, Timeline, Mindhunters, National Security, Bad Boys II, Redline, Project Gotham Racing 3, NHL 2003, Enter the Matrix, XGRA: Extreme-G Racing Association, The Hills Have Eyes 2, Crackdown, Need for Speed: Most Wanted, America's Next Top Model and Pimp My Ride.
