Pass Out of Existence is the debut studio album by American heavy metal band Chimaira, released on October 2, 2001.

Prior to the album’s release, the track "Dead Inside" was performed on the short lived USA Network program Farmclub.com.

[4] Pass Out of Existence features re-recordings of two songs that were included on the band’s previous release, This Present Darkness, which are “Sphere” and “Painting the White to Grey”.

In a 2004 interview, synthesizer player Chris Spicuzza acknowledged this but pointed out that it was largely an issue with the mixing that gives this impression.

This would later prove beneficial when drummer Ricky Evensand left Chimaira in 2004; going on advice from Slayer guitarist Kerry King, Mark Hunter contacted Kevin Talley who would go on to fill the role for two years.
