Crack the Skye is Mastadon's album that tells a story dealing variously with the art aesthetics of Tsarist Russia, astral travel, out of body experiences, and Stephen Hawking's theories on wormholes. The All Music Guide says the CD "rocks, and hard!", calling the guitar arrangements the "most intricate, melodically complex things the band has ever recorded." This guitar tab songbook features note-for-note transcriptions in notes and tablature for all 7 songs, including the title track and: The Czar; Divinations; Ghost of Karelia; The Last Baron; Oblivion; Quintessence.
