Water can retain or wash away memory; flowing or freezing. It gives life and shapes earth, while frozen imprints of an ancient past are waiting to melt – back into sound or fluid motion, or simply to dissipate and disappear. For their split release, Yoichi Kamimura and Olli Aarni offer two distinct reinterpretations of a performance recorded live at the Temppeliaukio Kirkko – a church in Helsinki built directly into solid rock and bathed in natural light – meditating on glacial landscapes and water cycles, using shared field recordings that bifurcate into two sonic visions of “ice journey”.

Yoichi Kamimura’s extensive recordings formed the bedrock of the original performance, notably from time spent on Suomenlinna Island just outside Helsinki in 2021, aiming to capture the remnants of the glacial movements that formed the area’s geology. Elsewhere, the voices of ringed seals, underground waterways of Kyoto, and icy rivers in Lapland from Kamimura’s library float in as well. “The small, charming, and gentle islands floating in the Baltic Sea—some with little cottages and restaurants—reminded me of the drifting ice in the Sea of Okhotsk between Japan and Russia,” describes Kamimura. Fragments of a Christmas choir creep in too, recorded at the church on Suomenlinna Island. Titled Kōri no ryokō , Kaimimura’s reinterpretation of the performance emphasises a shared future across all icy sea regions of the world: thawing ancient memories and the threat of disappearing entirely.

On Jäämatkailu, Olli Aarni presents his own expansive reworking of the same source material, heavily processed alongside his own field recordings from Vantaanjoki river and Suontee lake in Finland. “I was thinking about the processes of erosion, water carving rock, the prehistoric glaciers over the landscape in my own environment,” explains Aarni. The soundscape hums with both intimate details and macrocosmic flow, and a submersible bass rumble hinting at an iceberg far below the tip, morphing at time scales beyond human comprehension.
