American Tragedy Redux is the second remix album by American rap rock band Hollywood Undead, taking songs exclusively off the band's 2011 studio album, American Tragedy, and remixing them. The first remix album was the Black Dahlia Remixes album, featuring three remixes of Hollywood Undead's single, "Black Dahlia". The album was released on November 21, 2011 by A&M/Octone Records. The original tracks on the album, which were on American Tragedy, were recorded following the induction of Daniel Murillo into the band in early 2010 and lasted until December. The tracks were then remixed by various DJ's and musicians during the band's World War III Tour with Asking Alexandria later in 2011. The album's first single, "Levitate (Digital Dog club mix)", was released on October 18, 2011, with a music video being released on October 24.

Following the release of the band's second studio album, American Tragedy, the band announced a remix contest on August 11, 2011, where fans created their own remixes of the tracks "Le Deux" and "Bullet". The contest winner for the "Le Deux" was Dr. Eargasm, whose remix was chosen by the band and is featured on the album. The "Bullet" remix was voted as the best remix and was included on Redux as an iTunes bonus track. The band announced in October 2011 that a remix album, titled American Tragedy Redux, would be released on November 21, 2011 as their first remix album. The band created a series of online promotions for the album. First, they unlocked the track list and cover art for the album once the album title was tweeted 10,000 times on Twitter, which was accomplished by the end of the second day that the contest started. Then, the band released the first single, "Levitate (Digital Dog club mix)", on October 18 once the album art was shared 3,000 times on Facebook. A music video for "Levitate (Digital Dog club mix)" was released on October 24, 2011 through Virgin Mobile. The last Facebook unlock was a site for pre-ordering the album and ordering merchandise. The band also released the "Comin' In Hot (Wideboys Remix)" on the pre-order site. J-Dog said of the album, "This is our first remix record ever, we got to pick the DJ's and re-mixers that the band really likes. Who would have thought that someone you grew up listening to would one day remix your song?"
