Twenty One Pilots is a musical duo from Columbus, Ohio, formed in 2009. Their name is inspired by the Arthur Miller play All My Sons, in which 21 pilots are killed. You can watch a cool live performance of this song here. Fun fact: Tyler Joseph (lead singer) was working at a Killers concert back in 2009. When he was about to clean up he said to himself: “You know what, I want to be the next Brandon Flowers” and quit.
