Panic! At the Disco formed in Las Vegas in 2004, made up of a line-up of high school classmates. The band first sought a fan base through MySpace and their debut album 'A Fever You Can't Sweat Out' (2005) reached number 13 in the Billboard Chart. The two hit singles that followed, 'I Write Sins Not Tragedies' and 'But It's Better If You Do', a world tour in 2006, and performance with Bloc Party in the same year all cemented their success and in 2007 they began work on their follow-up album 'Pretty. Odd'. The album reached number two in the US and was followed by another world tour. However, despite their success, in 2009, it was announced that Ross and Walker had left the band due to musical differences but the band went on tour with various musicians from other bands taking Ross and Walker's places. 'Vices & Virtues', their third studio album, was released in 2011 followed by a tour of the same name and a collaborative tour with indie pop band Fun. In 2013 'Too Weird to Live, Too Rare to Die!' became their fourth album and was followed by the news of drummer Spencer Smith's departure. The band continued on with news of a fifth album, teased by the unexpected release of single 'Hallelujah' in 2015. The single debuted at number 40 on the Billboard Hot 100 and they followed up with 'Death of a Bachelor' and 'Victorious', both taken from the new album 'Death of a Bachelor' which was released in 2016. They recorded a version of Queen's 'Bohemian Rhapsody' for the 'Suicide Squad' soundtrack and announced a tour for 2017. Bassist Dallon Weekes took leave of the band in 2017 and they band played a surprise gig in Cleveland, Ohio with their new bassist Nicole Row. 'Pray for the Wicked', their sixth album, was released in 2018, preceded by two singles, 'Say Amen (Saturday Night)' and '(F**k a) Silver Lining'.
