Dimmu Borgir is a symphonic black metal band from Norway. "Dimmu Borgir" means "Dark Cities" or "Dark Fortresses" in Icelandic and Old Norse. The name is derived from a volcanic formation in Iceland, Dimmuborgir.
Dimmu Borgir started as a melodic black metal band in 1993. Formed by Shagrath, Silenoz, and Tjodalv, the band released an EP in 1994 entitled Inn i evighetens mørke ("Into the Darkness of Eternity" in English). This short EP sold out within weeks, and the band followed up with the 1994 full length album For all tid.
