Panic! At The Disco is an American rock band formed in 2004 in Las Vegas, Nevada. Originally a pop-punk group, the band’s style evolved over the years, incorporating elements of baroque pop, electronic music, and alternative rock. The band gained early fame with their debut album A Fever You Can’t Sweat Out (2005), which included the hit single I Write Sins Not Tragedies. Over time, Panic! At The Disco underwent lineup changes, with lead vocalist Brendon Urie becoming the sole member by 2015. Their later albums, like Death of a Bachelor and Pray for the Wicked, embraced a more pop-rock sound, with hits like Death of a Bachelor and High Hopes.
