Herja is roughly translated to «wage war» and is one of the two new albums by Danheim (2018).
Herja contains Viking War Songs and Epic Viking Battle Songs. In contrast to the Fridr album, Herja is based on a darker atmosphere and are inspired by the struggles, battles and hostile times of the Viking Age.
Wardruna is a Norwegian music group formed in 2003 by Einar Selvik along with Gaahl and Lindy Fay Hella.
They are dedicated to creating musical renditions of Norse cultural and esoteric traditions and make significant use of Nordic historical and traditional instruments including primitive deer-hide frame drums, flutes, kraviklyr, tagelharpe, mouth harp, goat horn, and lur. Non-traditional instruments and other sources of sound like trees, rocks, water, and torches are also used.
The band has released four full-length albums, the first three based on Norse mythology, the last based on the sayings of Odin from the Völuspá and other old norse sources.
