Bjørn' Arntsen is a researcher in music composition and sound engineering.

As a Sámi born New Zealander, Bjørn's music often blends Sámi syntaxes, rhythms and repetitions found in Joik with Māori vocabulary and has a strong focus and connection with mana whenua- indigenous land rights. He often blends the tradition of American minimalism with outside influences that include electronic dance music, hip-hop and alternative rock.

Born in Tromsø, Norway and educated in London, New York and New Zealand.

Bjørn also has an extensive background as a composer, pianist, recording engineer, editor and producer. His productions aim to bridge the gap between minimalist composers such as Reich, Glass and Pärt with the pioneering electronic music of Brian Eno, Kraftwerk, Aphex Twin and the Prodigy. The result is a body of work that encompasses music for television, film, theatre and the concert hall.

In August 2025, Atoll Records released Bjørn’s debut album, Bàrru, containing many of his works for chamber ensemble.

His compositional portfolio include works for chamber ensembles, string orchestra, concertos and an opera adaptation of Henrik Ibsen’s, A Doll’s House.
