Ronja moves through a sonically cinematic universe that gives reference to something decadent yet close to nature, with a style not too far aesthetically from artists such as Lana Del Rey or Billie Eilish. Ronja tells particularly contemporary stories revolving around love, power relations and the experience of a versatile feminine life force.

She has a long-standing background in music and has, among other things, attended the American Berklee College of Music, sung in a large number of some of Denmark's most prestigious choirs and received lessons from renowned music teachers. She has previously released two EPs and various singles.
