Crack the Skye CD

Crack the Skye is the fourth studio album by American heavy metal band Mastodon.
According to an interview on the DVD The Making of Crack the Skye, this album represents the element of aether, which is represented by the souls and spirits of all things, a theme closely related to the context of the album. Because the elements of fire, water and earth have already represented by the band's first three albums Remission, Leviathan and Blood Mountain, respectively, the element of air is the only classical element which has yet to be represented by a Mastodon album, as their follow-up studio albums The Hunter and Once More 'Round The Sun do not represent an element, nor are they concept albums.

Crack the Skye is the first studio album to feature drummer Brann Dailor as the band's third lead vocalist.
