aus + the humble bee Chalybeate

CAT No. FLAU110
Release Date: February 13th, 2026
Format: LP/CD/DIGITAL

aus が2024年秋に群馬・伊香保温泉に1ヶ月滞在・制作し、現地で公開され大きな話題を呼んだ八湯回遊型インスタレーション「いかほサラウンディング」。Chalybeateは、その展示をThe Humble Beeが丸ごと再構築し、音そのものを伊香保の空気と湿気に1年間浸し、再発酵させた作品です。温泉街全体を音の泉に見立て、源泉の湧動音、木造建築の反響、石段の賑わいや、あちこちに散らばる風鈴の音が重ねられ、町そのものの呼吸を写しとったというインスタレーション音源は、にごりのない澄んだモチーフから1年をかけてテープヒスのざらつきやひそやかなうねり、黄金と白銀で知られる伊香保の湯の質感が染み込んでいます。終わることのない石段で疲れ切った ausからミックスのバトンを受け取ったのは、長年にわたって付き合いを続けてきた英マンチェスターのアンビエント名手 Craig Tattersall。微かに湯の中でこだまする倍音を丁寧に掬い取った繊細なサウンドデザインによって、儚くアトモスフェリックな音響に仕上がっています。ビジュアルは、伊香保と同じ水源ともいわれる榛名の現地アーティスト フランシス・カナイによる湯らぐグラフィック。LPは温泉を模したハーフ・トランスパレントの特殊ヴァイナル、CDボーナストラックにはサウナの国フィンランドより、Olli Aarniのリミックスが追加収録。

Chalybeate began as a document of a month-long stay by Tokyo-based producer aus in Ikaho, a historic onsen town in Japan, during the autumn of 2024.
Working from field-recordings captured inside multiple ryokan baths, aus synthesized the subterranean movement of the onsen’s with local details: the bubbling of source water, the hoozuki (lantern plants) and furin (wind chimes) placed at each ryokan (inn), and the surrounding insects and birds. Rather than portraying Ikaho as a landscape, the recordings trace the town’s respiration.
The material was first presented on site as an installation called IKAHO SURROUNDING – AMBIENT ONSEN unfolding across eight different onsen, where visitors listened while soaking in roten-buro (open air hot baths). The project drew wide attention for proposing listening as a bodily act (音泉音浴), inseparable from heat, moisture, and duration.

Chalybeate re-constructs that installation as an album. The recordings were left to sit for a year within Ikaho’s air and humidity, allowing the sound itself to slowly change. The title refers to Ikaho’s iron rich mineral water, known as Kogane-no-yu (golden water), which oxidizes upon contact with air and leaves rust colored traces in its baths. Following this process, the album’s sound was repeatedly re submerged and re worked, gradually absorbing a corroded texture..tape hiss, gentle distortion, and subtle fluctuations rise quietly, like steam. What remains is not documentation but residue.
Mixing was handed over to Manchester based producer The Humble Bee by Craig Tattersall, because aus exhausted himself traversing Ikaho’s steep stone steps. The exchange mirrors the work itself: from bathtub to hot spring, from sound to something that surrounds the body.

Woodwind like tape noise and the movement of water dissolve into one another. The music does not arrive all at once. It settles slowly, as if lowering into warm water.
