Undoubtedly the most addictive number in the oft-spooky Of Monsters & Men arsenal, ‘Mountain Sound’ is so painfully catchy, the Icelandic hitmakers frequently use it to turn their live show into a clapping, howling battle of the sexes. Boasting a killer boy-girl chorus line that has absolutely nothing to do with mountains, it’s a jangley, spirited piece of folk-infused pop that’s equally appropriate for indie club nights and campfire singalongs.
