Swedish black metal band Grafvitnir have streamed "Vargavinter," from their new record Keys to the Mysteries Beyond. With their fifth studio album, the band is back from the cold shadows of Scandinavia to ignite the fire once again. Formed in 2007, Grafvitnir was formed in the dark forests of Sweden about ten years ago. The group has previously released four full-length albums. This record comes only a year after the release of their last album Obeisance to a Witch Moon.
