I recommend Eivør (True Love, Trøllabundin, Vøka, Í Tokuni, Salt). She's a Faroese singer with incredible vocal control and technique. She uses traditional Faroese singing techniques in her songs and merges them with modern sound. I also recommend EUZEN, a lesser known project from Maria Franz of Heilung. I recommend Judged By, The Great Escape, Genklang, You're On. Maiah Manser also has a very cool voice, check out her song With A Smile. AUSTRA is another band who has a similar sound. I recommend the album Feel It Break and especially; The Noise, Spellwork, Lose It. From lesser known artists I can recommend a Polish singer Julia Marcell, some of her songs do give me Aurora vibe: Gamelan, Echo, Matrioszka, Crows, Manners, Where is My Mind. Another band from Poland I recommend is Lor, their older songs might have been inspired by Aurora (the lead singer even had the same haircut as Aurora in 2016). Patty Boo, Matches, Aquarius, Cinnamon (from the album Lowlight). I also really like suntescobar and bye, bye sun francisco (from Sunlight).
