Radioactive

This song about self-rediscovery is the first single off American rock band Kings Of Leon's fifth studio album titled Come Around Sundown. The record was recorded in New York at Avatar Studios and was produced by Only By The Night producers Angelo Petraglia and Jacquire King.

Bassist Jared Followill told Billboard magazine that although the song has never been released, it has long been in the band's repertoire: "We played it forever. We started playing it around the time right after we wrote [2005's] Aha Shake Heartbreak. It was kind of in between Aha Shake Heartbreak and Because of the Times, and there was actually a few songs like that that didn't make it. You know, we save songs until we get them right."

A children's choir provide the song's background vocals. Jared explained its roots to Billboard magazine: "We went into the studio, we tried it, and it wasn't really working, and we were going to scrap the whole song. Then [lead vocalist] Caleb went back to an old spiritual song that we all sang growing up, and it matched up with the chorus so nice." Drummer Nathan Followill added: "Gospel music was a big part of us growing up, so to be able to come back and revisit that part of our lives at this stage in our lives is a pretty special thing."
