Bastille (stylised as BΔSTILLE) are an English indie pop band formed in 2010. They began as a solo project by singer-songwriter Dan Smith, who later decided to form a band. The four-piece is completed by Chris 'Woody' Wood, William Farquarson and Kyle Simmons. They recently added a touring member to the band, Charlie Barnes. The name of the band derives from Bastille Day, which is celebrated on 14 July, Smith's birthday.

After an independently released debut single and a self-released EP, the band signed to Virgin Records. Their first studio album, Bad Blood, was released in March 2013 and entered the UK Albums Chart at number 1. The band was nominated for four Brit Awards at the 2014 ceremony, winning the British Breakthrough Act. As of November 2014, Bastille have sold over 5 million records in the US and 2.5 million records in the UK.
