Shown above is the album cover, the main point of focus being the bent tree. This is supposed to be the oldest tree in the world, located in Chile, and I believe it symbolises the strength of the band, that they plan on being around for a long time. The bones hanging from the tree also suggest strength and age, and the barren location also suggests that their strength is their main focus, and nothing around them will distract them from that.
The text in the top left corner is bright yellow, standing out clearly against the sky-blue background, and is in Biffy's usual font, making it easily distinguishable as their own.
We can see that the back of the CD jacket has another tree, again symbolising strength and growth of the band. The side that shows the track listing has a close up shot of the branches of the tree. Again, yellow font is used to make the titles and important information on the cover stand out to the audience. At the bottom of this side is the familiar barcode as well as the copyright and licensing information in smaller print. This is so it doesn't distract the audiences attention from the main parts - the track listing.
