Panic! at the Disco

Consists of members Ryan Ross, Brendon Urie (singer, guitar, bass, keyboards), and Spencer Smith (drums). Bass player Brent Wilson left the band in May 2006 to pursue other things. Jon Walker soon replaced him as bassist. In 2009, members Ryan Ross (lyricists, guitar, backup vocals) and Jon Walker announced that they would be leaving Panic! At the Disco due the fact that they had "creatively evolved in different directions". Singer Brendon Urie and drummer Spencer Smith will pursue the group. Old members Ryan Ross and Jon Walker then created a new band called "The Young Veins", which is presently on hiatus.

The band was signed by Fall Out Boy bassist Pete Wentz and their album "A Fever You Can't Sweat Out" was released in September 2005. Their first single was "I Write Sins Not Tragedies" and their second was "But It's Better If You Do." They've toured on Nintendo Fusion in Fall 2005, Truckstops and Statelines in Spring 2006, and headlined in Summer 2006 with The Hush Sound, The Dresden Dolls, and Ok Go.

Childhood friends Ross, Wilson, and Smith originally created a band called Pet Salamander, then Summerleague Rock. Once Urie joined they become Panic! at the Disco (a name taken from a variation of a Smith's song).
