'Puzzle' is the fourth album by Biffy Clyro, released 4 June 2007. It was the band's first album since leaving Beggars Banquet. The album includes the singles 'Living Is A Problem Because Everything Dies' and 'Saturday Superhouse', which found the band breaking into the Top 15 for the first time in the UK , and received high critical acclaim with the NME. Mixed in New York by Andy Wallace (Nirvana, At The Drive-In) and with artwork by Storm Thorgerson (Pink Floyd, Led Zeppelin), Puzzle marks Biffy's transformation into a truly world-beating band. From the soaring 'Semi-Mental' to the bludgeoning punch of 'Saturday Superhouse' through the swollen intensity of the slow-burning 'As Dust Dances' and to the glorious foot-stomping live favorite 'Who's Got A Match?', Puzzle packs an emotional punch with 24-carat choruses shot through with Biffy's trademark sideways approach to songwriting.
