Drawing inspiration from Northern Europe's Iron Age, Heilung's themes, lyrics, and ambitious visual presentation evoke the Viking period in grandiose fashion. To pay tribute to their heritage, the Danish trio employ unique instrumentation in their music; ranging from running water via human bones, reconstructed swords and shields, ancient frame drums, bronze rings, and more. Their lyrics are taken from texts found in ancient rune stones, preserved spear shafts, amulets, poems, and other relics of a bygone era. On their debut Ofnir, Heilung's percussive, primal music is deeply ritualistic and truly embodies amplified history. In April 2018, Season of Mist will reissue Ofnir and live recording Lifa, originally released in 2015 and 2017 respectively, as gatefold 2LP-sets.
