Panic! at the Disco (stylized for a time as Panic at the Disco) is the stage name/moniker of American pop/rock singer and multi-instrumentalist Brendon Urie. The project originally began as a band in Las Vegas, Nevada, formed in 2004 by childhood friends Urie, Ryan Ross, Spencer Smith and Brent Wilson. Live, Urie is currently joined by bassist Dallon Weekes (who was also formerly a full-time member of the band), guitarist Kenneth Harris, and drummer Dan Pawlovich.
Panic! at the Disco recorded its first demos while its members were in high school. Shortly after, the band recorded and released its debut studio album, A Fever You Can’t Sweat Out (2005). Popularised by the lead single, “I Write Sins Not Tragedies”, the album eventually was certified double platinum in the US and sold over one million copies. In 2006, founding bassist Brent Wilson was fired from the band during an extensive world tour, and subsequently replaced by Jon Walker.
In 2015, Smith officially left the band after not performing live with the band for several years due to health and drug-related issues. Shortly thereafter, it was announced that Weekes would revert to being a touring member once again, leaving Brendon Urie as the sole trader and songwriter under the Panic! At The Disco name. On April 20, 2015, Urie released “Hallelujah” as the first single from Panic! At The Disco’s fifth studio album. The album, Death of a Bachelor, was released worldwide on January 15, 2016.
