........The members of Panic! at the Disco had barely graduated high school when their full-length debut, A Fever You Can't Sweat Out, transformed the suburban Las Vegas teenagers into national emo-pop stars. The band had materialized several years earlier, when friends Spencer Smith (drums) and Ryan Ross (guitar) began covering blink-182 tunes together. After tiring of playing another group's material, the duo recruited two additional classmates, guitar/vocalist Brendon Urie and bassist Brent Wilson, and the newly-formed quartet decided to model its name after a line in Name Taken's "Panic." Crafting pop-influenced songs with theatrical touches, quirky techno beats, and perceptive lyrics, Panic! at the Disco posted several demos online that soon caught the attention of Decaydance Records, the Fueled by Ramen imprint headed by Fall Out Boy's Pete Wentz. Even though the band had yet to play a live show, they subsequently became the first band signed to the label.

With their record scheduled for a release in September 2005, Panic! at the Disco joined the successful Nintendo Fusion Tour and hit the road alongside Fall Out Boy, Motion City Soundtrack, Boys Night Out, and the Starting Line. The band continued to tour into early 2006, while their single "I Write Sins Not Tragedies" found its way into TRL hearts and the Billboard Top 40. Proving to be a popular lineup, the Nintendo tour (which also featured Hellogoodbye, "Acceptance," and the Academy Is...) consistently sold out venues across the country. Wilson was fired from the group mid-year; undaunted, Panic! pressed on with their friend Jon Walker on board for a full summer tour that culminated with appearances at Lollapalooza, Reading, and the Leeds festival. The guys picked up "Video of the Year" at MTV's annual VMA ceremony, beating out heavy hitters like Madonna and the Red Hot Chili Peppers, and a collector's box set version of Fever (featuring random Panic paraphernalia and a DVD) came out just in time for the 2006 holiday season. After additional tour dates, the band announced that they were eliminating the exclamation point from their name, a sign that seemed to foreshadow the mature, less emo-driven rock featured on Pretty. Odd. Released in March 2008, the sophomore album peaked at number two in the U.S. and showcased an evolving band whose tastes had grown to encompass the Beatles' psychedelic pop. The group supported the album with another string of show dates, one of which was captured on the CD/DVD release ...Live in Chicago. ~ Corey Apar, All Music Guide
