Mastodon - Crack the Skye (2009)

Introducing the idea of nautical metal, Mastodon's breakthrough album "Leviathan," was based on Moby Dick. If only the premise of their newest album were so simple: Wormholes, time travel, Tsarist Russia, underground Christian sects, Rasputin and battles with the devil all figure into the story. Nonetheless, it's actually a good album. Listen: "Crack The Skye"HANDOUT
