​​Chosho Hakkei in Rittor Base - HPL ver, which won a Prix Ars Electronica 2021 Digital Musics & Sound Art Honorary Mention, originated from three works presented in the sound exhibition Chosho Hakkei held in 2019 at Nakazu Banshoen Garden and Marugame Museum of Art in Kagawa Prefecture. evala reconstructed these three works into an 8.1.2-ch. spatial audio work at Ochanomizu Rittor Base in February 2020, and released it as a stereophonic streaming/downloadable sound source using HPL, a technology that allows listeners to experience 3D sound through headphones. This time, evala will return to Rittor Base in Ochanomizu for an online live performance titled “Chosho Hakkei in Rittor Base - Live Performance ver” using the 3D sound system and high-definition video system.

Chosho Hakkei in Rittor Base - HPL ver

​​Chosho Hakkei in Rittor Base - HPL ver is a creation based on Chosho Hakkei, a sound exhibition held in 2019 at Nakazu Banshoen Garden and Marugame Museum of Art (organized by Nakazu Banshoen Garden Hosho-kai, curatorial director ABE Kazunao), set in a Japanese garden with over 330 years of history. It was an experimental project to transform a historical cultural asset with the power of radical sound art, in which evala presented three works that intersected space and time axes, composed with original binaural audio technology based on sounds recorded around Lake Biwa and real-time environmental sounds in the garden, which are associated with the eight sceneries of Omi. In February 2020, these works were presented as a 45-minute seamless 8.1.2-ch. spatial audio remix at the Rittor Base in Ochanomizu. Chosho Hakkei in Rittor Base - HPL ver was released as a stereophonic streaming/downloadable sound source using HPL, a technology that allows users to simulate 3D sound with headphones.

Director’s comment

​​The term “sound artist” is not enough to describe what evala creates. The founder of See by Your Ears, evala is a pioneer in evoking deep perceptions through the act of listening. He is an artist and an artisan who manipulates the latest technology, while never compromising in creating works of art even with challenges that future technology may cause. His spatial view of the musical world leads to the evolution of innovative sound technology and methods. Chosho Hakkei, a work that was first performed in a 330-year-old garden in Japan that embraces all things in nature, will be delivered live from a new concept of a teahouse specially designed for this event with an unseen barrier, an experience that transcends time and space.
