BJ Nilsen

BJ Nilsen is a Swedish sound artist and composer based in Amsterdam whose work explores the intersection of field recording, sound, space, and perception. Through subtle electronic manipulations and detailed editing, he transforms environmental recordings into layered, immersive soundscapes that inhabit the space between reality and abstraction. His practice spans original scores and sound design for music, film, visual arts, and performance across a career of more than thirty years.

He began releasing music in 1991 under the moniker Morthond on Sweden's Cold Meat Industry label.
