Biffy Clyro are a Scottish rock band that formed in Kilmarnock, East Ayrshire comprising Simon Neil, James Johnston and Ben Johnston. Currently signed to 14th Floor Records, they have released six studio albums, three of which, Puzzle, Only Revolutions and Opposites reached the top five in the UK Albums Chart. They also claimed their first number one album in the UK Albums Chart with their sixth studio album, Opposites.
After their first three albums, the band expanded their following significantly with the release of their fourth, Puzzle in 2007 creating more mainstream songs with simpler rhythms and distancing themselves from their more unusual dissonant style that was present in the previous three albums. Puzzle peaked at number 2 on the official UK album charts on 16 June 2007. The album went Gold in the UK, selling over 100,000 units and later went Platinum in the UK in 2012 selling over 300,000 copies. Biffy Clyro's popularity was built upon further in 2008 and 2009 with the release of the singles "Mountains" and "That Golden Rule", which both reached the top 10 of the UK Singles Chart.
Their 2009 album, Only Revolutions, reached No. 3 in the UK chart and went gold within days of its release in 2009, later going platinum in 2010 and was nominated for the Mercury Music Prize. 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 number eight on the UK Singles Chart after The X Factor 2010 winner, Matt Cardle covered the song. It became the UK number one Christmas single for the year of 2010. In 2011 the band was nominated for the Brit Award 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 Leeds & Reading Festival. 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.
