Asalaus (Ása Önnu Ólafsdóttir, she/her, b. 2000) is a sound artist, musician, and composer from Reykjavík, Iceland. Her practice focuses on the relationship between objects and sound. She frequently uses magnetic materials, such as tape, in her work, and the material itself often guides the process and determines the outcome of a piece.

As a composer and musician, she works with graphic notation, extended techniques, and the integration of live electronics. She has released several albums, both as Asalaus and as a member of the bands Ateria and Gaffer Ensemble. Ása’s works have been commissioned, exhibited, and performed widely across Europe and the United States. She currently lives and works in New York while completing her MFA in Sound Art at Columbia University.
