[5] In January 2014, band members David Draiman (vocals), Dan Donegan (guitar), Mike Wengren (drums) met for dinner and began secretly writing material for Disturbed's sixth studio album.

Bass player John Moyer was not present for the album's making, due to working with other bands and projects.

"[9] One of the bonus tracks, "Legion of Monsters," was inspired by Rolling Stone's August 2013 cover featuring then-accused Boston Marathon bomber Dzhokhar Tsarnaev.

David Draiman wrote an angry condemnation of the magazine for "glorifying killers" in a lengthy Facebook rant.

Due to the murders of Alison Parker and Adam Ward, Warner Bros. Records decided to pull one of the television commercials for the album as the ad depicted an incident similar to the killings.

[12] James Christopher Monger from AllMusic gave the album a three out of five stating, "A five-year break between albums should lend itself to a bit of growth, even for a band as everyman as Disturbed, but there's just not much here to keep the group's detractors from bringing out their pitchforks, and over time, staying the course may leave fewer and fewer townsfolk to protect them.

"[17] Jon Hadusek from Consequence of Sound was highly critical of the album giving it a D rating and saying "In this way, Immortalized is a for-fans-only release.

Lamb of God found a balance between the two with their latest album, VII: Sturm und Drang, which shines as a recent example of how to move forward artistically and still appeal to one's core fans and sell records.

[22] On January 25, 2018, Immortalized had been certified platinum by the RIAA in the United States, signifying sales in excess of over 1,000,000 copies.

The AMC show Into the Badlands features Disturbed's version of "The Sound of Silence" in episode 13 of season 3 ("Black Lotus, White Rose").
