There is a pivotal moment on Biffy Clyro’s second album when lead singer Simon Neil—amid the helter-skelter fretwork of “When the Faction’s Fractioned”—starts to augment his lyrics with little yelps and grunts. These improvised barks of delight point to a confidence that reverberates through The Vertigo of Bliss. Whether it’s the throat-stripping call-to-arms that is “Bodies In Flight” or the delicate harmonies on “Diary of Always” this is a record that takes things up several notches and affirms the Ayrshire trio’s winning formula of lyrically tender rock maximalism.
