Danger Days: The True Lives of the Fabulous Killjoys is the fourth and final studio album by American alternative rock band My Chemical Romance. Like its predecessor, The Black Parade, the album was produced by Rob Cavallo. It was released by Warner Music and Reprise Records on November 22, 2010.
The final edition of the album and its music videos are set in a fictional post-apocalyptic California in the year 2019 (resembling the film Blade Runner), in which a few outsiders dubbed 'Killjoys' are engaged in conflict with a nefarious corporation that seemingly controls the population. The 4 Killjoys are Party Poison, Fun Ghoul, Jet Star, and Kobra Kid.
The promotional tour for the album, The World Contamination Tour, lasted from October 2010 to February 2012 and saw concerts in Europe, America, Asia and Oceania. Danger Days topped the Billboard Rock Albums and Alternative Albums charts, and peaked at No. 8 in the overall Billboard 200 with 112,000 first week sales, as well as appearing in charts in numerous other countries. As of February 2011, Danger Days has sold over one million copies worldwide.
