Angantyr started as a synth/ambient projekt in 1997. It quickly developed into a raw blackmetal band, and in 1998 the first demotape "Endeløs" was recorded. "Endeløs" contains 5 tracks of ear-mutilating blackmetal.

The debut CD "Kampen Fortsætter" was recorded in the year 2000. The sound has improved, and the first song ever recorded "Stilhedens Larm" is included, Along with a re-recording of "Da frostvind blæste" from the first demo.

In 2001 The second demotape "Nordens Stolte Krigere" was recorded in a small shed in the forest of Egebæksvang. This tape was made as a dedication to the Swedish band Domgård, who was imprisoned for their honorable deeds.
