Olsen was born in
Brøndby in 1985 and produced mostly in the
electronic genre until 2016, when a strong interest in
Norse mythology led him to start combining that with his music. Since 2016, Danheim has released eight records on his own independent label. His style has been described by reviewers as "
Brian Eno doing the soundtrack for
Game of Thrones" Lyrically, his music deals with such tales from Norse mythology such as
Hrungnir's fight with
Thor, the story of
Fimbulwinter and much more. In 2019, Danheim also contributed music to the soundtrack of three episodes from the second half of the sixth season of the
History Channel series
Vikings. One of the actors from the show,
Georgia Hirst, enjoyed Danheim's contributions to the score so much that she released a social media video praising his music. his
YouTube channel had 555,000 subscribers and received more than 220 million video views. In March 2020 Danheim released his third full-length album of 11 tracks, . He decided to release the album earlier than planned, to help entertain his fans under lock-down or in isolation due to the
COVID-19 pandemic. Reviewers praised the album's "visceral and hypnotic" composition, and noted the varied instrumentation that produced a "multidimensional Viking soundbath". Teemu Esko of Kaos Magazine called "versatile and touching, while rich and immersive". == Discography ==
