Puzzle is the fourth studio album by Scottish rock band Biffy Clyro, released 4 June 2007 – the album was later released in America in August. It is the band's first album since leaving Beggars Banquet (though the sleeve artwork still features the Beggars Banquet logo). This album is notable for having somewhat more straightforward song structures and a more melodic overall sound than their previous work, while still retaining some more unusual elements.
