Biffy Clyro are a Scottish rock band from Kilmarnock, comprising Simon Neil (guitar, lead vocals), James Johnston (bass, vocals) and Ben Johnston (drums, vocals). 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 the 16th of June 2007. The album went gold in the UK, selling over 100,000 units. 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 latest album, Only Revolutions, reached #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.
The first incarnation of what would eventually become Biffy Clyro was formed in 1995 by fifteen-year-old Ayr-based guitarist Simon Neil, who recruited Kilmarnock-born Ben Johnston and someone known as Barry on drums and bass respectively, calling themselves Screwfish. Barry was soon replaced by James Johnston, Ben's twin brother, and the three spent the next two years rehearsing, writing and covering songs.
