Biffy Clyro (colloquially referred to as Biffy) are a Scottish rock group from Ayrshire whose members are Simon Neil (lead vocals, guitar), James Johnston (vocals, bass guitar) and Ben Johnston (vocals, drums). Although the band have always had a dedicated following and have been around since the mid-1990s as well as producing an EP and four albums, it is only in 2007 with their fourth album, Puzzle that they have found real commercial success. This album is seen as less heavy and experimental, and more widely accessible and has won wide critical acclaim, however many of the fans that had followed the band for a long time have not warmed especially to the new direction of their music. Puzzle has been championed on TV and radio, and Biffy have promoted it with a tour and many festival performances over the summer of 2007 (including a snippet of a live performance being used as the opening titles for the BBC coverage of T in the Park).
Biffy's sound is a heavy but melodic mixture of guitar, bass and drums, with all three band members contributing to vocals. They are known for complex and interwoven guitar picks, strums and melodies, that change many times within each track. "'Mon the Biffy!" is a well known chant among Biffy fans; usually shouted in between songs at gigs, or before the band comes on stage.
