Mastodon’s new album Crack The Skye is streaming now at the band’s MySpace page.

Out through Warners/Reprise on March 23rd, the album’s seven tracks run for about 50 minutes and boast titles including ‘Oblivion’, ‘Divinations’ and ‘Czar, The (I) Usurper, (II) Escape, (III) Martyr, (IV) Spiral’.

Looking to address the perceived lack of focus of previous album Blood Mountain, Crack The Skye is based around “a unified concept in which an astral traveller wanders the spirit realm, exploring themes from quantum physics to Czarist Russia”.
