Wukir Suryadi is an Indonesian experimental musician, composer and instrument builder, born in Malang in 1977 and currently based in Salatiga, Central Java. Also known as a co-founder of the duo Senyawa, he develops an interdisciplinary practice at the intersection of craft, sound installation and radical performance. His work has been presented at venues including the Weltkulturen Museum, STEIM – Studio for Electro-Instrumental Music, Kyoto Art Center and the National Gallery of Victoria, as well as at the Asian Art Biennial, Jakarta Biennale and Biennale Jogja.

At the centre of his practice are original instruments constructed from natural materials, everyday objects, and elements of machines and tools. Structures such as Bambu Wukir, Garu, Industrial Mutant and the Sustainable Sonic Engine allow him to create a wide spectrum of sounds — from meditative, subtle structures to intense, post-industrial distortions. For Suryadi, working with materials also becomes a way of addressing environmental issues and the relationship between humans, technology and their surroundings.

At Avant Art Festival, the artist will present the solo performance TITIR ON THE PODIUM: A Dialogue between Złoty and Opłatek, performed on the Sustainable Sonic Engine — an experimental instrument whose main body is made of bamboo. In the piece, Suryadi enters into a wordless dialogue with the material and cultural symbols of Poland, contrasting the weight and coldness of the złoty with the fragility and spiritual significance of the opłatek.

The performance moves from intimate, meditative tensions towards an intense, mechanical sound of a post-industrial character. Its successive stages — Nginguk, Sopo Ingsun, Industrial Mutant and Siklus dan Doa — create a space for reflection on materialism, the fragility of human relationships and the global ecological crisis. Rather than offering a closed narrative, it is an invitation to a shared ritual of concentration, perseverance and spiritual regeneration through sound.
