Thorr's Hammer was formed in Ballard, Seattle, Washington by Greg Anderson and Stephen O'Malley during winter 1994–1995.

The band reached its final form when Jamie Sykes and James Hale joined.

The band was active only for six weeks[1] during which it played two gigs and recorded a demo and an EP titled Dommedagsnatt.

In 1997, the song "Troll" from their EP Dommedagsnatt was released on The Awakening - Females in Extreme Music,[2] a compilation album from Dwell Records.

In an interview with Rock-A-Rolla magazine, Runhild Gammelsæter said the band "might make some new music" in the future.
