Danger Days: The True Lives of the Fabulous Killjoys is the fourth studio album by My Chemical Romance, released in 2010. It is a concept album set in a post-apocalyptic California in 2019, with the band members playing the rebel group the Killjoys. The record sounds more colourful and pop-oriented than its predecessor The Black Parade, with influences from punk, power pop, and electronic music. Singles included Na Na Na (Na Na Na Na Na Na Na Na Na), Sing, and Planetary (GO!). It was the band's last studio album before their 2013 split; the group reunited in 2019.
