Vintersorg is a Swedish band from Skellefteå, formed in 1994 under the name Vargatron . Musically, Vintersorg has covered a wide number of heavy metal genres; while the band is mostly rooted in extreme metal styles, particularly black metal and Viking folk metal, it has also expanded into progressive metal and avant-garde metal. Lyrically, the band deals with topics on fantasy, mythology, nature, the cosmos, and metaphysics. Vintersorg means "Winter Sorrow," but the name was taken from the The Legend of the Ice People series by Margit Sandemo, where the character Vintersorg is the son of a great pagan leader.
