Postiljonen has managed to create a characteristic sound, where ethereal and alluring vocals are interwoven in a mystical, ambient, dreamy and lovable expression. Postiljonen is often compared to the likes of M83, Sigur Rós, JJ and Cocteau Twins.
Postiljonen released their highly praised first studio album Skyer in 2013 and the follow-up Reverie in 2015. Their style is often compared to M83 and sometimes The Naked and Famous. The group describes themselves as nostalgic dreamers.
