Fall Out Boy is an American rock band formed in Wilmette, Illinois, a suburb of Chicago, in 2001. The band consists of vocalist, keyboardist and guitarist Patrick Stump, bassist Pete Wentz, guitarist and keyboardist Joe Trohman, and drummer Andy Hurley. While Fall Out Boy's music has been typically described as pop punk and pop rock, the band were generally seen in the mid-2000s at the forefront of the "emo pop" explosion. A central part of Fall Out Boy's sound is rooted in the band's lyrics, mainly penned by bassist Pete Wentz, who commonly uses irony and other literary devices to narrate personal experience and stories. The name "Fall Out Boy" was chosen when the band asked the crowd in their second show what their name should be and an audience member shouted out "Fallout Boy," the name of The Simpson's fictional superhero, Radioactive Man's sidekick.
