With much anticipation for the album after 2006's Christ Illusion, members of Slayer were revealing information about the album since early 2009. There were four different artworks released for the album, each which completed one-fourth of a map, that when put together, illustrates the earth painted with red. There are eleven tracks on the album, with origins illustrating death and destruction, war, serial killers, and the Apocalypse. It is the band's first studio album to be played mostly in E-flat
