Najaaraq Vestbirk (b. 1987) is a Greenlandic-born artist based between Copenhagen and Berlin. Her multidisciplinary practice investigates affective histories of electronic dance music with a particular focus on the trance genre. Spanning composition, DJ-ing, performance and video work, Vestbirk approaches the aesthetics of trance from a therapeutic angle, exploring how bodily movement, emotional catharsis, and utopian sociality can coalesce as healing in dance floor contexts. Under the moniker Courtesy, Vestbirk has toured extensively as a DJ, having performed in distinguished venues and festivals around the world such as Berghain, Bassiani and Sónar by Night. She is the founder and creative director of Kulør, a record label and multidisciplinary artistic platform that since 2018 has produced records, books, exhibitions, and programming across the music and contemporary art worlds.
