[1] Astrid Sonne was born and raised in Bornholm, a small island of Denmark.

She joined a strict classical training before quitting at 18, moving to digital composition — she learned how to use Ableton Live by herself.

After discovering Danish musician Hari Shankar Kishore, known professionally as DJ HVAD, Sonne started refining an electronic style that focused more on melody than on percussion.

[2] On 16 February 2018, Astrid Sonne released the album Human Lines, where she tried to combine her classical upbringing with electronic composition.

[16] She later formed the duo Coined alongside Fine Glindvad, a Danish lo-fi folk musician.
