Vinterskugge is the first full-length release by the Norwegian black metal band Isengard. It is actually a combination of three demo tapes released between 1989 and 1993, which explains the difference in sound between the releases, with the earlier recordings predating the second wave of black metal and resembling death metal more closely. Isengard is a solo project of Fenriz, famous for being the drummer of Darkthrone, created in 1989.
