Mastodon, the Atlanta-based metal band, has always been known for their ability to weave personal tragedies into their music. Their ninth album, Marrow Deep is no exception. Recorded just a week after the untimely death of founding guitarist-vocalist Brent Hinds the album is a raw and emotional journey through grief and loss.
The band has a history of channeling personal tragedies into their music. From the death of their manager Nick John on their previous album Hushed and Grim (2021) to the loss of guitarist Bill Kelliher’s mom on Once More ‘Round the Sun (2014), Mastodon has consistently used their music as a form of catharsis. Marrow Deep continues this tradition, with the band grappling with the loss of Hinds and drummer-vocalist Brann Dailor’s mother in February 2025.
The Emotional Core of Marrow Deep
The album opens with Barbarian’s Blood a track that immediately sets the tone with its crushing riffs and desperate vocals. Vocalist-bassist Troy Sanders growls, We don’t get over this a line that resonates with the raw emotion of the album. The song Ghost Again is particularly poignant, with Dailor singing about seeing Hinds’ ghost and the crushing feelings of regret that follow.
The album is a tribute to Hinds, a bandmate who was crucial to their beginning but lost his way. It’s also an acknowledgment of life’s frailty. The music is heavy, with crunching, gnashing riffs that close out tracks like Ghost Again. But it’s also weirdly emotional, at least for a metal album. The band’s turmoil is evident in every note, making Marrow Deep a deeply personal and cathartic experience.
The Evolution of Mastodon’s Sound
Marrow Deep bears all the sonic hallmarks of Mastodon’s discography—raspy, bellowed vocals, chunky to viscous riffage, off-kilter rhythms, and solos galore. But there’s something different about this album. The band’s adventurous soloing comes even more to the fore, with keyboardist João Nogueira and lead guitarist Nick Johnston keeping the original trio on their toes.
The album features a mix of styles, from the drowning riff of Barbarian’s Blood to the gut-shaking rhythm guitar of Golden Spires. The band’s prog rock influences are more prominent than ever, with echoes of synth- and keyboard-driven bands like Pink FloydDeep Purple and even Yes. Nogueira’s keyboard work adds a new dimension to the album, from creepy, John Carpenterish analog synth to Dream Theater-like wheedling.
The guitarists work through their feelings with bluesy motifs, pyrotechnic eruptions, and long, breathy phrasing. The album also features a deep guest list, with cameos from heavies like GojiraLamb of GodQueens of the Stone Age and Clutch. The intro to The Vanishing played by Black Sabbath’s Geezer Butler is a standout moment, with Butler’s riffs setting the tone for one of the album’s best songs.
The Cathartic Power of Marrow Deep
Marrow Deep is a turbulent, ornate, measured, chaotic, and ultimately cathartic album. It’s a testament to Mastodon’s maturity as a band, with the callow rage and aspirations of badassery that prompted them to write Leviathan about Moby-Dick replaced by a deeper, more introspective approach. The fates and furies here are Mastodon’s own, uncontrollable and unique.
The album’s standout track, The Vanishing features Dailor aping Ozzy Osbourne’s vocal effect from Sabbath’s Planet Caravan. The song is a poignant reflection on loss and remorse, with Sanders singing words that capture the crippling remorse he and his bandmates feel. The song ends with Sanders screaming, a raw and emotional climax to a deeply personal track.
In the end, Marrow Deep is a powerful and emotional journey through grief and loss. It’s a testament to Mastodon’s ability to turn personal tragedy into a profound musical experience. The album is a must-listen for any fan of Mastodon or metal in general, offering a raw and emotional exploration of the band’s deepest feelings.
