With an almost supernatural voice - previously described as a more vocally gifted version of Lana Del Rey's - Ronja moves through a sonically cinematic universe that gives reference to something ancient and close to nature, not too far aesthetically from the enigmatic Danish folktronica group Sorten Muld. However, Ronja tells particularly contemporary stories revolving around love, power relations and the experience of a versatile feminine life force, all told from the perspective of a modern woman.

She has a long-standing musical background 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 an EP and two singles.
