A Swedish sound artist and composer based in Amsterdam, BJ Nilsen explores the intersections of field recording, sound, space, and perception. Through subtle electronic manipulations and detailed editing, Nilsen transforms environmental recordings into layered, immersive soundscapes that inhabit the space between reality and imagination.

His new album True than Nature (2025), released on Ideologic Organ, builds on a 30-year career creating original scores and sound design for music, film, visual art, and performance. The Slovak Radio Hall will host the concert premiere of this material in a special multi-channel version.

Nilsen began releasing music in 1991 under the moniker Morthond on the Swedish label Cold Meat Industry. From 1998 to 2015, he released works as Hazard and under his own name on the UK labels Ash International / TOUCH.

Over the years, he has collaborated with a wide range of artists including Chris Watson, Jóhann Jóhannsson, Hildur Guðnadóttir, Karl Lemieux, Anla Courtis, Judith Hamann, Franz Graf, Anthea Caddy, Z’EV, and many others. His latest album, Irreal (2021), was released on Editions Mego.

Organized by A4 as part of the New Perspectives for Action project within the international collaboration Re-Imagine Europe, co-funded by the European Union and supported using public funding by the Slovak Arts Council and Bratislava City Foundation.
