Panic! at the Disco's short career breaks down into three distinct periods. First, armed with an exclamation point, theatricality and teenage angst, they recorded high-speed pop punk album "A Fever You Can't Sweat Out" in 2005.

Panic! at the Disco's short career breaks down into three distinct periods. First, armed with an exclamation point, theatricality and teenage angst, they recorded high-speed pop punk album "A Fever You Can't Sweat Out" in 2005.

Next came the no-exclamation-mark phase. With the release of "Pretty. Odd.," the band dropped both the punctuation and bassist Ryan Ross. The new music sounded like their label told them, "Be more like the Beatles." Think mid-tempo, with chimes, strings and "Sgt. Pepper's"-like harmonies.

The punctuation has been reinstated for 2011's "Vices & Virtues." The band - now with only two members - has returned to the sound of "Fever," except there's a little more maturity. And singer Brendan Urie finally seems to have stopped wearing eyeliner.
