The band started with the childhood friends Ryan Ross, a singer and a guitarist, and Spencer Smith, as a drummer. Both of them went to the same school Bishop Gorman High School, and they use to play music together since they were in 9th grade. Ross and Smith invited their mutual friend Brent Wilson from a nearby school Palo Verde High School to join them as a bassist, and later Brent invited this classmate Brendon Urie to be the guitarist of the band.
They started making music in Smith’s grandmother’s living room. In initially years, Ross was the lead singer for the band, but later, Urie replaced him as the group came to know during rehearsals that he can sing better, so they decided to make him the lead singer of the band when they started Panic! At the Disco was a cover band of Blink-182.
Panic! At the Disco aimed to be different from the other metal bands in Las Vegas, U.S., the group was lucky to sign a recording contract even without having performed in any live show. Urie started working at Tropical Smoothie Cafe in Summerlin as a part-time so that he could afford a practice space for the band. Urie had to work since he was kicked out of his house by his parents because he dropped out of high school. Urie also sang for tips during his working hours. All four member of the band left their educations studies to concentrate on music.
