At the Water Plaza of Expo 2025 Osaka, Kansai, Japan, Symphony of Water and Air, the daytime fountain show, was presented daily throughout the Expo period. Inspired by Yoko Kanno’s wish to “make the most of the sound of a real live piano here,” the music from Under the Midnight Rainbow, the main water spectacle show, was newly reimagined as two-piano arrangements. Performed and recorded live in a single take by Yui Morishita and Benyamin Nuss, these arrangements became Piano Symphonia Blue and Piano Symphonia Red. Alternating from one hourly performance to the next, Blue and Red were played throughout the day, captivating countless visitors alongside the fountains.
This product is a piano duo sheet music set featuring both pieces. The score has been supervised and finalized by Yui Morishita himself, who co-arranged the music with Yoko Kanno and also performed in the recording.
