Panic! at the Disco emerged in the mid-2000s sounding a lot like pop-punk peers Fall Out Boy, whose Pete Wentz signed the band. Since then, though, Panic! has shapeshifted in both lineup and sound. The new Pray for the Wicked is a relentlessly fun and over-the-top pop album on which singer Brendon Urie (now the band’s only official member) deploys tricks he learned performing on Broadway last year. With Arizona and Hayley Kiyoko.
