Mastodon - Crack the Skye (Black Vinyl)

2009 release from the Atlanta-based Heavy Metal outfit. Mastodon has taken hold of the leadership of the New Wave of Progressive Heavy Metal. 

Crack the Skye, it's fourth original studio album, mines subject matter from czarist Russia and astral travel to out-of-body experiences and Stephen Hawking's theories on wormholes for an unrepentantly heavy aural assault that will shake the heavens.
