Diatom

Low Light

A Gdansk quartet's second album of melodic, cinematic post-metal, big clean melancholy over genuine weight. Its best half breathes beautifully, its loudest peaks a little less so.

Diatom describe their own record as an exercise in “poisoned romanticism,” and for once the band-speak is accurate. Low Light is the second album from the Gdansk four-piece, and it lives in the space where post-rock’s yearning meets post-metal’s heaviness, all cinematic swells and deep, melancholy clean vocals riding over a low end you can feel in your chest. The cover, a still grey lagoon full of grinding pack ice, is the whole album in one image: cold, pretty, and quietly crushing.

The band is at its best when it trusts the quiet. “For Mercy” is the clearest example, a warm, dynamic track where the drums keep an honest, roomy character, the bass growls up out of the foundation with real presence, and Michal Kulniew’s low, grave vocal sits perfectly centred and unforced. “Until” does something similar, opening with chorus-drenched clean guitars as texture before hardening into the wall, and “Everlasting” is the cleanest-sounding thing here, balanced and open with the cymbals given actual air. When Diatom let the arrangement stretch out, the songwriting carries it, and the melancholy lands without ever tipping into melodrama.

Where the album loses a little of its footing is at the top of its own dynamic range. Several of the heaviest passages have been pushed hard into the master, and “Riverbeds,” “The Northern Veil” and “Met” all narrow into a dense, compressed block right where they should open up, the transients flattened and the bass swallowed by a saturated guitar wall that trades definition for sheer size. It is a common post-metal problem and not a fatal one, but on a record that proves elsewhere how good it sounds when it breathes, the over-compressed peaks are a self-inflicted limit. The quiet-to-loud contrast that is the genre’s whole engine works best when the loud part still has room to move, and here it occasionally does not.

None of that undoes the record, because the core of it is genuinely affecting. Diatom write melodies that stick, they resist the temptation to drown everything in reverb for its own sake, and Kulniew’s voice gives the whole thing a human centre that a lot of instrumental-leaning post-metal lacks. Low Light is a well-made, emotionally direct second album that knows exactly what mood it is chasing and catches it more often than not. Tighten the hand on the master at the peaks and the next one could be something special. As it stands, it is a cold, handsome, quietly sad record worth sitting inside for its fifty minutes.

Melodic, cinematic post-metal built on the contrast between yearning post-rock quiet and genuine heaviness, carried by deep, grave clean vocals. It sounds best when it breathes: “For Mercy” is warm and dynamic with an honest roomy kit and a bass that growls up with real presence, “Until” moves from chorus-drenched clean guitars into the wall, and “Everlasting” is the most balanced and open track, cymbals given real air. The recurring flaw is at the loud end: “Riverbeds,” “The Northern Veil” and “Met” narrow into a dense, over-compressed block exactly where they should open up, transients flattened and the bass swallowed by a saturated guitar wall. The clean-to-heavy contrast that drives the genre works best when the heavy part still has room to move, and here it sometimes does not. Affecting melodies, a real human centre in the vocal, undercut only by over-limited peaks.
