Crack the Skye
Crack the Skye is the fourth studio album by American progressive metal band Mastodon, released on March 24, 2009, through Reprise Records.[1][2] The album is a concept record that explores themes of astral projection, out-of-body experiences, and spiritual journeys, drawing inspiration from historical events like the assassination of Grigori Rasputin and Tsarist Russia, as well as personal tragedy.[3][4] It forms the culmination of Mastodon's elemental tetralogy, representing the classical element of aether (or spirit), following Remission (earth), Leviathan (water), and Blood Mountain (fire).[5][6] The narrative centers on a paraplegic protagonist's astral travels, weaving in motifs of healing and transcendence, partly motivated by the suicide of drummer Brann Dailor's sister Skye at age 14, to whom the title pays homage.[7][8][9] Produced by Brendan O'Brien and recorded primarily at Southern Tracks Studios in Atlanta, Georgia, Crack the Skye features intricate songwriting with progressive structures, psychedelic influences, and a blend of heavy riffs, soaring melodies, and clean vocals, marking a shift from the band's earlier sludge metal roots toward more melodic and expansive compositions.[10][11] Upon release, it debuted at number 11 on the Billboard 200, selling over 41,000 copies in its first week, and garnered widespread critical acclaim for its emotional depth, musicianship, and conceptual ambition.[12][13][14] Reviews praised its masterful integration of heaviness and melody, with outlets like Drowned in Sound highlighting its "mightily muscular and meticulously masterful musicianship" and Prog Archives calling it an "excellent release."[13][15] The album has since been regarded as a landmark in progressive metal, influencing subsequent works and celebrated through anniversary editions, including a 15th-anniversary deluxe release in 2024.[16][10]Background and recording
Development
Following the release of their 2006 album Blood Mountain, which concluded Mastodon's elemental-themed concept trilogy, the band sought to pivot toward a more narrative-driven approach for their next project, eschewing the fire-water-earth progression in favor of a unified storyline centered on personal and cosmic exploration.[17][18] A core inspiration for Crack the Skye stemmed from drummer Brann Dailor's personal tragedy: the 1990 suicide of his sister Skye at age 14, an event that profoundly shaped his life and the album's emotional core as a lasting homage to her memory.[19][18] Dailor explained, "My sister Skye’s suicide is something I’ve been dealing with for 20 years. I wanted to lift her up and put her name out there forever."[18] This personal loss intertwined with broader conceptual influences, including Stephen Hawking's theories on black holes and wormholes, the historical figure of Rasputin, and czarist Russia's mysticism, all evoking themes of astral projection and out-of-body experiences drawn from Dailor's own psychedelic explorations.[20][18] The writing process began in 2007, with guitarist Brent Hinds emerging as the primary musical architect, while Dailor handled most lyrics in collaboration with the band, crafting a loose narrative about a paraplegic protagonist embarking on an astral journey through time and space to escape his physical limitations.[18][21] This collaborative effort emphasized thematic unity over rigid structure, allowing the story to unfold across the album's tracks. To achieve a more polished production than the rawer sounds of prior releases, Mastodon selected Brendan O'Brien as producer for the first time, drawn to his Atlanta connections and recent work on AC/DC's Black Ice, aiming for a timeless, layered aesthetic reminiscent of progressive rock classics.[18]Recording process
The recording of Mastodon's fourth studio album, Crack the Skye, took place primarily at Southern Tracks Studios in Atlanta, Georgia, during 2008, following initial writing sessions that began in late 2007 after guitarist Brent Hinds recovered from a severe head injury sustained earlier that year.[22][23] The sessions extended into early 2009 for finalization, spanning roughly 18 months in total development and production.[24] Producer Brendan O'Brien played a pivotal role in shaping the album's sound by streamlining the band's complex progressive structures through meticulous arrangements and emphasizing the raw energy of live band performances.[25][23] O'Brien guided the group in identifying essential elements for each song, using Pro Tools to edit and refine tracks while encouraging the four members to record together as a unit to preserve their organic interplay, as guitarist Bill Kelliher noted: "Brendan was good at figuring out what we needed and what we didn’t."[23] This approach helped translate the band's ambitious compositions into a cohesive 55-minute runtime across eight tracks, balancing intricacy with accessibility.[26] The process was marked by significant challenges, including Hinds' ongoing recovery from his 2007 accident, which created uncertainty about the band's future and delayed cohesive rehearsals, as Kelliher recalled: "We didn’t know what the state of the band was."[23] Drummer Brann Dailor described the intense rehearsal sessions as "a bit like torture," stemming from the shift to more atmospheric, emotionally charged material that diverged from their earlier high-energy style and weighed heavily on performances due to the personal themes involved.[20] Despite these hurdles, the band pushed forward, incorporating multi-layered guitar textures—such as ambient drones, 12-string acoustics, and baritone guitars on tracks like "Ghost of Karelia"—alongside vocal harmonies and subtle orchestral flourishes via keyboards played by O'Brien to enhance the psychedelic depth.[23] Guest appearances included Neurosis frontman Scott Kelly providing additional vocals on the title track, adding a raw, atmospheric edge.[27] In post-production, O'Brien handled the mixing at his Los Angeles studio, drawing from his extensive gear collection to achieve polished tones, with assistance from engineers Nick DiDia and Billy Bowers on additional recording and editing.[26][27] The album was mastered to highlight its dynamic range, resulting in a sonic landscape that captured the band's evolving vision while retaining their signature intensity.[25]Composition
Musical style
Crack the Skye represents Mastodon's evolution into progressive metal, blending psychedelic and sludge metal influences with expansive song structures that extend beyond their earlier riff-heavy approach. The album features intricate compositions, exemplified by the 10:54 epic "The Czar," which unfolds through layered sections and thematic development.[28] This shift emphasizes longer, narrative-driven tracks over the concise aggression of prior works like Leviathan (2004).[29] The music incorporates complex time signatures and abrupt dynamic shifts, transitioning from crushing heavy riffs to atmospheric melodic interludes, evoking progressive rock pioneers such as King Crimson and Pink Floyd.[30] Guitarists Brent Hinds and Bill Kelliher deliver dual-layered riffs and intricate solos, supported by Brann Dailor's versatile, polyrhythmic drumming and Troy Sanders' propulsive bass lines. Experimental elements include synthesizers and Mellotron, adding psychedelic textures to the sludge core.[31][14] Produced by Brendan O'Brien, the album achieves a cleaner, more polished tone than the raw intensity of Leviathan, balancing metallic heaviness with broader accessibility while maintaining sonic cohesion through recurring motifs that link tracks into a unified concept piece.[29][32]Lyrical themes
The lyrics of Crack the Skye form a conceptual narrative centered on a paraplegic protagonist who engages in astral projection to escape his physical limitations, traveling through space via a golden umbilical cord emerging from his solar plexus.[22] This journey leads him into a wormhole, transporting his soul to a spirit realm where he encounters ethereal beings who direct him to a Russian cult for guidance.[22] There, his essence merges with the historical figure Grigori Rasputin, who attempts to challenge the Russian czar before being assassinated, allowing the intertwined souls to flee through a mystical "crack in the sky(e)" back toward earthly redemption.[22] The overarching themes revolve around death, rebirth, and spiritual transcendence, portraying the soul's arduous quest to reunite with its body while confronting obstacles like the Devil.[22] Key symbols enrich the storyline, with black holes and wormholes serving as portals between dimensions, drawing from concepts in quantum physics such as those explored by Stephen Hawking.[33] Russian mysticism and occult elements, including Rasputin's enigmatic role in historical lore, underscore the narrative's ties to esoteric traditions and near-death experiences.[18] The title itself evokes a rupture in the celestial barrier, symbolizing breakthrough amid despair.[22] On a personal level, the album is deeply inspired by the suicide of drummer Brann Dailor's sister Skye at age 14, serving as a metaphorical exploration of grief, the desire to intervene in tragedy, and overcoming addiction—reflected in guitarist Brent Hinds' own history with heroin and a near-fatal coma.[18] Dailor has described the lyrics as a way to process two decades of unresolved pain, transforming personal loss into a tale of salvation.[18] The writing process was collaborative, with all band members contributing lyrics to infuse the record with collective emotional depth and transcendence.[20] Track overviews highlight the narrative arc without revealing resolutions: "Oblivion" initiates the astral escape and confrontation with cosmic voids; "Divinations" establishes the cult's prophetic role in guiding the lost soul; "The Czar" interweaves historical Russian intrigue as a pivotal interlude; while later tracks like "The Last Baron" and "Crack the Skye" build toward spiritual climax and return.[22] Broader philosophical undertones incorporate occultism through Rasputin's shamanistic aura and quantum ideas of multidimensional travel, emphasizing existential questions of consciousness and the afterlife over literal biography.[18]Artwork and packaging
Cover art
The cover art for Crack the Skye was created by artist Paul Romano, who had designed the visuals for Mastodon's previous albums Remission, Leviathan, and Blood Mountain, establishing a consistent visual language for the band.[34] Romano's design adopts a psychedelic, cosmic aesthetic, employing deep blues, bright reds, and varied textures to evoke an ethereal, otherworldly realm that mirrors the album's exploration of astral travel and spiritual dimensions.[35] At the center stands a robed, Rasputin-like figure with a beard, seated in a metallic frame without legs—one arm robotic—holding magical spheres above his hands while mystical light emanates from his mouth, symbolizing the duality of souls, divination rituals, and the astral traveler's journey through the ether.[36] The swirling, multi-colored cloud background and central black hole represent cosmic voids and black holes, tying directly to themes of out-of-body experiences, time travel, and the void between dimensions, while subtle nods to turbulent Russian politics appear through symbolic elements like a bear denoting strength and healing.[35][36] The design process was collaborative, with Romano extracting abstract concepts from the album's lyrics—such as astral projections and historical mysticism—and rendering them in a handmade, collage-style technique to achieve a vintage progressive rock vibe, complete with the Mastodon logo integrated amid flames, seeds, waves, and elemental symbols.[35] While the standard edition uses the primary cover image, limited editions featured variations, including a deluxe tunnel book packaging with exclusive additional artwork and three-dimensional wormhole designs that enhanced the immersive, cosmic narrative.[37][38] Inner sleeve details in these editions incorporated further mystical symbols, reinforcing the album's thematic depth without altering the core cover aesthetic.[39]Physical formats
The standard physical release of Crack the Skye was issued on compact disc in a jewel case format, featuring an 8-page booklet that includes full lyrics integrated with artwork elements from the album's cover design.[40] The CD edition was distributed by Reprise Records in the United States, with co-labeling from Sire Records and Relapse Records in various markets.[41] The vinyl version appeared as a double LP pressed on 180-gram heavyweight vinyl, housed in a gatefold sleeve that accommodates the two-disc set and includes an inner sleeve with additional artwork and credits.[31] Special editions expanded on these formats with limited-run variants. Relapse Records oversaw select pressings, including colored vinyl options such as the 2009 red-and-gold edition limited to 650 copies.[41] A digipak version of the CD was released as the limited Royal Edition digibook double CD in the US, featuring the standard album and an instrumental score version.[41][42] Other limited vinyl pressings included 2010 tour-exclusive splatter editions in green and red (totaling 1,500 copies) and a 45 RPM mastering over two 12-inch discs bundled with a bonus CD, limited to 2,500 copies worldwide and including occasional inserts like a guitar tab card for "Divinations."[31][43] International variations primarily differed in labeling and minor insert details, with Reprise handling the US release and Sire Records managing European distributions, though core packaging like the jewel case booklet remained consistent across regions.[41] No significant artwork alterations were noted between these markets. Post-2009 reissues included further limited vinyl editions, such as a 2015 opaque light blue pressing in Europe and a 2017 picture disc available in the US and Europe.[41] The 2024 15th anniversary edition featured a remastered double LP on 180-gram colored vinyl (options including sky blue and smoky grey), presented in a gatefold sleeve with updated packaging that incorporates a 12-page 12x12-inch booklet, a 24x24-inch poster, and custom magnets in deluxe boxes.[44]Release and promotion

The album represented Mastodon's first major label release, co-pressed with their longtime independent partner Relapse Records, signaling a pivotal shift from their indie roots.[41] Available formats at launch included standard CD, digital download, and vinyl editions, with limited variants such as a CD/DVD bundle and colored double LP.

No significant delays marred the rollout, though the partnership dynamics highlighted the band's evolution from underground metal to broader commercial accessibility.[47][12]Marketing and touring
To promote Crack the Skye, Mastodon released teaser previews and conducted interviews highlighting the album's conceptual narrative of astral projection and spiritual exploration. In early 2009, the band shared exclusive audio snippets and video interviews with outlets like SPIN, where members discussed the record's thematic depth and production with Brendan O'Brien.[48][49] A trailer for the conceptual companion film Crack the Skye: The Movie was unveiled in 2011, further emphasizing the album's cinematic storyline.[50] For the album's 10th anniversary in 2019, Mastodon launched a multi-part behind-the-scenes documentary series titled The Making of Crack the Skye, consisting of four episodes that included archival studio footage and contemporary band commentary on the creative process.[51][52] The second single "Oblivion" received an official music video directed by Roboshobo, featuring surreal visuals that intercut band performance footage with dreamlike sequences of cosmic travel and existential imagery to mirror the album's themes.[53] A remastered HD version was released in 2024 as part of anniversary promotions.[54] The title track "Crack the Skye" was later accompanied by an official visualizer in 2019, depicting animated ethereal journeys aligned with the song's astral motifs.[55] Mastodon's 2009 Crack the Skye Tour headlined North American dates from April to May, performing the full album alongside select older material, with support from Kylesa and Intronaut.[56][57] The band also appeared at major festivals including Coachella, Download Festival in the UK, Bonnaroo, and the inaugural Rock on the Range, extending promotion into summer.[58] Following the U.S. leg, they joined Metallica's European tour as openers in June.[59] In 2019, to mark the 10th anniversary, Mastodon embarked on the Unheavenly Skye Tour, a co-headlining run with Coheed and Cambria, where they played Crack the Skye in its entirety each night, accompanied by new animated visuals retelling the album's story on stage screens, with support from Every Time I Die.[60][24] The 26-date U.S. trek ran from late May to early July, starting in Louisville, Kentucky, and concluding in Irving, Texas.[61] No dedicated anniversary tours for Crack the Skye were announced between 2020 and 2025, though the band continued general headlining activity.[62] Merchandise tied to the album included themed apparel and posters featuring Paul Romano's cosmic artwork, such as bear motifs and ethereal designs, available through official channels since 2009.[63] Special edition bundles emerged for anniversaries, including the 2019 10th-anniversary picture disc vinyl paired with apparel and the 2024 15th-anniversary deluxe box sets containing remastered LPs, Blu-ray content, t-shirts, and posters.[24][44] Limited collector's packages, like a 2025 Revolver Magazine super bundle with multiple vinyl variants, apparel, and prints, further extended promotional tie-ins.[64]Reception and legacy
Critical reception
Upon its release in 2009, Crack the Skye garnered widespread critical acclaim, aggregating a Metacritic score of 82 out of 100 based on 29 reviews, reflecting near-universal praise for its ambitious scope and execution.[65] Pitchfork rated it 8.0 out of 10, lauding the album's organic blend of progressive rock elements into Mastodon's metal foundation, creating immersive tracks like "The Last Baron" with dynamic shifts and cathartic choruses, though it critiqued the record for feeling less intense and expansive than predecessors such as Leviathan.[66] Rolling Stone awarded 4 out of 5 stars, highlighting the band's evolution into prog-metal territory with intricate guitar arrangements and rhythmic complexity, exemplified by the 13-minute epic "The Last Baron."[67] AllMusic emphasized the album's headphone-worthy immersion, praising its melodically complex guitar work and cohesive conceptual narrative as the band's most intricate recording to date.[32] Kerrang! ranked it #4 among the top 20 albums of 2009, celebrating its epic proportions and musical melodrama, though some reviewers noted occasional overreach in its technical ambition, with one observing that the band's drive to surpass prior efforts could make certain passages feel labyrinthine.[68] Overall, critics acclaimed the album for its conceptual depth—drawing on themes of astral projection, Rasputin, and out-of-body experiences—and emotional maturity, positioning it as Mastodon's breakthrough into mainstream recognition while retaining progressive metal's edge.[66] Retrospective assessments have solidified Crack the Skye's status as a landmark in progressive metal. In 2019, marking the 10th anniversary, Revolver described it as a "creepy classic" in a behind-the-scenes documentary series, underscoring its visionary storytelling and sonic unpredictability as enduring hallmarks of the band's peak creativity.[52] Publications like Dark Matter Webzine echoed this, calling it a favorite that exemplifies music's potential across genres.[6] By 2024, the 15th anniversary reissue prompted renewed praise for its remastered soundscapes as a high watermark of elite musicianship and influence on modern prog-metal.[69] Reviews highlighted its lasting impact, such as in Spinema's unboxing analysis, which deemed it a magnificent record whose instrumental versions further reveal its structural brilliance.[70] A minor divide persists between critics and some fans, who occasionally lament a perceived dip in raw heaviness compared to earlier sludge influences, favoring its atmospheric maturity instead.[71]Accolades and commercial performance
Upon its release in March 2009, Crack the Skye debuted at number 11 on the US Billboard 200 chart, selling 41,395 copies in its first week and marking a 72% increase over the debut week sales of Mastodon's previous album, Blood Mountain.[12] In the United Kingdom, the album peaked at number 34 on the Official Albums Chart, spending two weeks in the top 100.[72] Internationally, it achieved moderate success, entering the top 20 in several markets including Australia. By September 2010, the album had sold 200,000 copies in the United States alone, establishing it as one of Mastodon's strongest commercial performers to date. The album's accolades highlighted its critical and industry recognition within the metal community. It earned a nomination for Album of the Year at the 2010 Revolver Golden Gods Awards, competing alongside releases from Heaven & Hell and Lamb of God.[73] Terrorizer magazine included it in their Top 40 Albums of 2009 critics' choice list, praising its innovative blend of progressive and heavy metal elements.[74] In retrospective rankings, Loudwire placed Crack the Skye at number 7 on their Top 25 Progressive Metal Albums of All Time and featured it prominently in their best progressive metal albums of the 2000s.[75][76] Crack the Skye has demonstrated significant longevity through catalog sales and digital streaming, bolstered by anniversary editions. The 10th anniversary in 2019 saw the release of special merchandise and a documentary film on its creation, renewing fan interest.[24] A deluxe 15th anniversary reissue in October 2024, featuring a remastered version, instrumental mixes, and live recordings, drove a sharp sales increase, with over 3,200 physical copies sold in the United States during its debut week— a nearly 7,500% jump from the prior frame.[77][78] As of late 2025, streaming platforms continue to amplify its reach, contributing to ongoing revivals among progressive metal audiences.[78]Credits
