This is 1184 - played live sadly without Valfar on vocals.

Valfar set out on foot to his family's secluded cabin at Fagereggi and never arrived. His worried family contacted local authorities, who organized a search party and, on the 17th, found Valfar's body at Reppastølen in the Sogndal valley. Apparently surprised by the inclement weather and deep snow, he had attempted to turn back toward home, but died from exposure and hypothermia on the way. Needless to say, these tragic events sadly spelled the end for Windir, whose remaining members solemnly organized a benefit concert to celebrate their lost leader, as well as a final CD (2004's Valfar, Ein Windir) containing Windir outtakes and leftovers meant to raise funds for Valfar's family
