excerpt from last.fm: Biffy, as they are often referred to, utilise a quiet/loud dynamic, constructing songs that can range from a whisper-quiet pick on the guitar, to huge walls of noise with massive distortion and crashing drums. While Simon Neil sings lead, all three members provide vocals. “’mon the biffy!” is a well known chant amongst Biffy fans; it is usually shouted in between songs at gigs, or before the band come on stage.
