If the live persona of Biffy Clyro—shirtless, sweat-drenched, full-bearded—perhaps paints them as mere amp-wrecking cavemen, this third record serves as a cerebral corrective. Not that Infinity Land, named after a Jeffrey Dahmer quote, is lacking in blood-and-thunder (exhibit A: the brooding, electro-inflected “Glitter and Trauma”). But from the key change catnip on “Some Kind of Wizard” to an unexpected blast of horns on “The Weapons Are Concealed”, this is a daring attempt to add engaging intricacy to the Biff’s abiding clatter.
