Isengard is a solo project by Fenriz. The heavily Tolkien influenced Isengard, the project logo being a depiction of Thuringwethil from 'The Silmarillion', bowed in with a death metal demo 'Spectres Over Gorgoroth' in 1989 and the follow up 1991 session 'Horizons'. Fenriz released another demo, 'Vandreren', in 1993, and Isengard switched to a folk style of black metal. Isengard compilation 'Vinterskugge' (Winter Shadow) was issued in 1994 on the Peaceville Records subsidiary Deaf Records and contains all the three demos.
