Mizuki Ishikawa @fun_k_son is a Berlin-based improviser and sound artist. In her improvisations with objects and DIY electronics, she manipulates the acoustic environment of a space using everyday objects and feedback techniques, while simultaneously exploring the conditions of performance through simple gestures and ordinary activities. Through improvisation, Mizuki aims to integrate the space, the audience, herself and time into a cohesive experience.
Romain C. Bertheau @threadeddreams_tm , aka ゴマサン and ThreadedDreams™, is a composer, pianist, organist, and experimental musician whose work explores acoustic instruments and electronic sound through the no-input mixer. His practice combines contemporary composition and radical improvisation, treating each instrument as a living entity and each performance as a dialogue with the space it inhabits. His work emphasizes subtle textures and the detail of sound.
Winona Lin @zweimau established Zweiart, launched as a group of interdisciplinary / sound artists and ongoing as performances and the monthly ‘Series Full Moon Experience’. Her and other like-minded artists, work together as an art group set to explore contemporary artistic materials and expressions within the fields of Sound Art, performance and Sonic concerts.

This work is an illustration of a song by my friend. Yes, there is Goma. I met him when he was playing noise music in Solo on July 12 last year. Actually, I like his songs on Soundcloud. And I was interested in illustrating his songs. So, he gave me several of his songs to choose from. I listened to each song one by one, and you know what? I fell in love with the song titled “Darkness Within.” The song offers a unique experience. When listening to this song, I feel as if I'm in another world, it feels mystical, it feels scary but at the same time peaceful.
Goma is not alone in this project. He plays this music with Jacek Chmiel and Syvlain Monchocé. He says that inspiration comes from the place where they played, a large church without light, in absolute darkness
As I said before, this song is so mystical and peaceful. I feel as if I am inside the song and feel solemn in praying to God. For me, this song is a reflection of humanity towards God. For me, it is a form of art to return to God. Maybe my opinion differs from yours. Because this is very subjective. You can listen to it on Bandcamp. Also, you can check their profiles on Bandcamp.
