Biffy Clyro are a Scottish rock band that formed in Kilmarnock, East Ayrshire, composed of Simon Neil (guitar, lead vocals), James Johnston (bass, vocals), and Ben Johnston (drums, vocals). Currently signed to 14th Floor Records, they have released nine studio albums, five of which (Puzzle, Only Revolutions, Opposites, Ellipsis and A Celebration of Endings) reached the top five in the UK Albums Chart, with their sixth studio album, Opposites claiming their first UK No. 1 album. The latest three consecutive studio albums have all peaked at number one in the UK official albums chart. After their first three albums, the band expanded their following significantly in 2007 with the release of their fourth album, Puzzle, creating more mainstream songs with simpler rhythms and distancing themselves from the more unusual dissonant style present in their previous three albums. Puzzle peaked at No. 2 on the UK Albums Chart on 16 June 2007. The album went platinum in the UK in 2012, having sold over 300,000 copies. The band released Only Revolutions in 2009 which reached No. 3 in the UK chart and went gold within days of its release in 2009, going platinum later in 2010 (achieving double-platinum status in August 2011) and receiving a Mercury Music Prize nomination. Only Revolutions included the UK hit singles "Mountains", "That Golden Rule", and "Many of Horror", all of which reached the UK Top Ten. The latter reached No. 8 on the UK Singles Chart after The X Factor 2010 winner, Matt Cardle covered the song, and became the UK number one Christmas single for the year 2010. In 2011, the band was nominated for the Brit Awards for Best British Group. At the 2013 NME Awards, they received the award for Best British Band. On 25 August 2013 Biffy Clyro headlined the main stage at Reading and Leeds Festival. Their sixth studio album, the double album Opposites was released in 2013, and was their first No. 1 album. Their seventh studio album, Ellipsis also reached number one upon release in 2016. Based on their album and single certifications, the band have sold in excess of 1,240,000 albums and 400,000 singles in the UK alone. A Celebration of Endings was released on 14 August 2020, and debuted at number one on the UK Albums Chart on 21 August 2020. As of 2021, in total, the band have spent 165 weeks in the top seventy-five of the UK Album Charts, with three of those weeks being at the top position at number one and 76 weeks within the main top forty of the albums charts. The band's singles have spent a total of 79 weeks in the UK Singles Charts, with six weeks in the top ten and 42 in the top forty.
