[9] The album was inspired by the events that took place during the war in Iraq with songs such as "Ashes of the Wake" (which includes snippets of former Marine Staff Sergeant Jimmy Massey in an interview after his return from the Iraq War), "Now You've Got Something to Die For", "One Gun" and "The Faded Line".

[11] Ten years after its release, as of 2014, sales have topped 400,000 copies sold and is Lamb of God’s best-selling record.

The Japanese edition included a bonus song "Another Nail for Your Coffin" which was released worldwide in 2010 in a three-CD box set called Hourglass: The Anthology.

The DVD side contained the album in LPCM 2.0, and Dolby Digital 5.1 surround sound, as well as various video clips, including the promo videos for "Now You've Got Something to Die For" (intended to promote the Killadelphia release) and "Laid to Rest", a short on the New England Metalfest, a "Meet the Band" and a clip from the Terror and Hubris DVD.

A production error in the 5.1 mix of "Break You" causes the vocals to be displaced throughout the track, and pitch shift high and low throughout the song.
