The only thing larger than the resplendent, celestial compositions of New York’s Iapetus is the galaxy itself. Set on a cosmic microwave backdrop of Dark Tranquillity-flavored guitar theatrics and titanic progressive death metal pieces reminiscent of Ne Obliviscaris¹, previous records The Long Road Home and The Body Cosmic were explorations of humanity and its deep, inseparable connection with the universe. Among the flood of soul-touching lyricism, The Body Cosmic‘s “I Contain Multitudes” proclaims with enlightened certainty, ‘where does the weight of the universe lie / if not with me?’ The Mother Void is the third and final installment in the conceptual arc that began with their debut; how do co-writers Matthew Cerami and Jordan Navarro end their long road home?

Iapetus are known for penning through-composed, ultra-maximalist epics, and The Mother Void is no exception: drums indulge in indefatigable blast beats and all-encompassing double-kicks, guitars tremolo and wail across the boundless void, and a hearty mix of clean and harsh vocals add equal parts abrasion and elegance. Compared to The Body Cosmic, The Mother Void is parsimonious in its use of spoken word, opting instead to rely more on lyricism to scaffold their point-of-view. In between supernova bursts of progressive melodeath, Iapetus stabilize on gentle, spacious interludes focused on clean guitars (“The World Be Undone”), synthesizers (“Aniara”), and atmospherics (“TON”).

The ineffable grandeur of The Mother Void must be matched with a careful compositional approach and attention to peaks and valleys. The title track is the best example of this, building on the momentum sparked by Fabienne Erni’s radiant performance on intro “Parturition”, as a mounting drum roll builds into gloriously somber black metal tremolos; Iapetus ride the crests and troughs of a gamma ray burst until reaching a zenith of overlapping harsh and clean vocals and an enormous open drum rhythm. “Red Giant” features many of Iapetus‘ finest moments to date, including an utterly gorgeous flamenco instrumental break and stop-and-go verses which cleverly morph around the track’s establishing ideas. Of the quieter moments on the record, the soft synthesizers halfway through “Aniara” evoke the ethereal warmth of Steve Roach‘s “Structures from Silence”.

Iapetus are careful on “The Mother Void” to deliver the track’s central message at its climax. A hefty guitar-led interlude leads into light-speed riffage and cutting death metal drumming, which then opens into a massive instrumental where Erni poses the following question to the listener:

What will you be—with infinity at your feet?
Aphelion cradle, the burden to bear;
What will you do—to spite the abyss?
Synodic reveries, the seductions of sleep.

Born from the void, we are given no guidance or instructions, and the unlimited, featureless expanse is a source of deep existential dread. At the same time, the endless possibilities offer empowerment: we have unlimited opportunity to dream, feel, and create, so we must do everything in our power to overcome our challenges and live a life of passion and fulfillment. Snippets of “Aniara” build beautifully off of the lyrical exploration of “The Mother Void”:

We paint across the void;
kaleidoscope colors hide
the coal-black maw;
we dance for a world destroyed.

But other verses feel unnecessarily baroque, detracting from the track’s messaging of holding on to hope in the face of imminent destruction through a (likely unintentional) knottiness:

But rapture’s end—chimera faults;
artifice soul melts canvas to mirror,
no refuge from you; the palette abused;
necromance fingers; the terminal muse;
the immolant film-burn death of display.

Despite the occasional lyrical misstep, Iapetus beautifully use galactic imagery as a canvas to explore human nature and its inseparable relationship with the cosmos, penning some of the most touching lyrics of the year.

The Mother Void‘s lyrics also act as a compositional nexus, with tracks depending strongly on the lyrics to support the songwriting. This approach reveals an irony in the record’s infinite grandeur: the lyrical climaxes of many songs are often when the music itself is comparatively subdued. These moments are by no means calm, but against the aggression of the surrounding compositions, they don’t burst with intensity in the same way. Nonetheless, these “climaxes” are still undoubtedly cinematic and satisfying in their own way once the proper context is given—”Aniara” sticks out in particular as it effectively captures the feeling of a spaceship disintegrating into dust in its final moments—but the equally fervent moments that surround them and that permeate The Mother Void can feel like a kneecap to the record’s dynamism.

“TON” suffers the greatest from narrative confusion: the track begins with an unfathomably huge verse, gracefully gliding through slick instrumental breaks and majestic harsh-clean vocal interplay, culminating in one of the most powerful solos of Iapetus‘ career. Halfway through, however, the track completely changes course to a hefty, Gojira-esque groove to center the second movement. Both parts are thoroughly engaging and have their own self-contained highs and lows, but the track as a whole ends up feeling overcooked, comprised of two unrelated parts that loosely orbit ideas of accepting death.

Additionally, some sections of the record feel a bit incomplete in their sparsity. The quieter sections that live on the bookends of “Red Giant” and “Aniara”, along with the tracks “Énouement” and “The World Be Undone” to a lesser extent, are pleasant but lack an atmospheric heft to them, feeling more like loose connective tissue to unrelated ideas as opposed to a critical component to the record’s flow. A focus on weaving movements more closely together—along with a trimming down/bolstering of the more toothless interstitials—would go a long way to unveiling the glorious potential that resides within The Mother Void.

In their tenure, Iapetus have gifted us extremophiles some of the most astonishingly grand music this side of the underground, and The Mother Void is a worthy addition to their repertoire. Though the occasional element feels a bit tepid and others over-engineered, when the balance between compositional acumen and immensity is struck, a sublime celestial beauty spills forth inviting the listener into its grand design. While no record can offer universal appeal, The Mother Void effortlessly offers Universal appeal.
