Panic! at the Disco is an American pop rock band from Las Vegas, Nevada, formed in 2004 by childhood friends Brendon Urie, Ryan Ross, Spencer Smith and Brent Wilson. Since 2015, singer Urie has been the only official member of the band, with drummer Dan Pawlovich, bassist Nicole Row, and guitarist Mike Naran accompanying him on tour. Panic! at the Disco recorded their first demos while they were in high school. Shortly after, the band recorded and released their debut studio album, A Fever You Can't Sweat Out. Popularized by the second single, "I Write Sins Not Tragedies", the album was certified triple platinum in the US. In 2006, founding bassist Brent Wilson was fired from the band during an extensive world tour and subsequently replaced by Jon Walker.
The band's second album, Pretty. Odd., was influenced by 1960s rock bands the Beatles, the Zombies, and the Beach Boys, and was preceded by the single "Nine in the Afternoon". That album marked a significant departure from the sound of the band's debut. Ross and Walker, who favored the band's new direction, departed because Urie and Smith wanted to make further changes to the band's style.
