Norwegian post-rock outfit Spurv have announced their fourth full-length album, Kelolågen, alongside the unveiling of its lead single, Kelogadd.

Driven by electronic percussion, bass, and breathy vocals, Kelogadd incorporates heavily processed field recordings of a waterfall captured in northern Norway’s old-growth forests. The single marks a sharp shift toward dark, noisy post-punk, introducing lead vocals for the first time in the band’s fifteen-year history, performed by founder Gustav Jørgen Pedersen.

The album’s title takes its name from the Sámi-derived Norwegian term for centuries-old pine trees that have died, dried, fallen, and slowly decayed back into the soil over hundreds of years. Spanning six tracks, Kelolågen traces the complete life cycle of a kelo tree, following earlier explorations of peatlands on 2018’s Myra and glaciers on 2023’s Brefjære.

Kelolågen leans into a more concise, dense structure, paring back extended build-ups in favor of immediate arrangements. Writing duties expanded across the six-piece line-up, with guitarist Eirik Ørevik Aadland co-writing the progressive riff work, trombonist Simen Eifring authoring the string arrangements, and pump organ layered into the mix. Recording and mixing were handled by Jørgen Smådal Larsen at Paradiso Studio in Oslo, with mastering completed by Magnus Lindberg (Cult of Luna).

Kelogadd is out now, with Kelolågen scheduled for release on February 5th, 2027, via Pelagic Records.
