Local fellowship led the band to record two Morbid Scream cover songs on their 2nd and 3rd LPs, first "The Coming of War" and then "Morbid Scream". Also recorded was a Hallstattian Swords 7", which remained unreleased until Mythological Occult Metal: 1991-2001.

Absu's releases go by conceptual cycles; the first two albums are based on Sumerian mythology, while The Third Storm of Cythraul, In the Eyes of Ioldanach and Tara form a trilogy about old Celtic mythology. After a hiatus of five years the band returned in 2009 with Absu, the first part of a new trilogy based on magick and occultism.

Formerly known as Dolmen, which evolved via Azathoth, Eternus and Necrotic into Absu in 1990. They call their style "Mythological Occult Metal", with "Absu" referring to a subterranean ocean in Sumerian mythology. The band draws on Sumerian, Celtic and other ancient mythologies, supervised by Proscriptor.

Proscriptor was given an opportunity to audition for Slayer on February 7th, 2002 in Dallas, Texas. While he wasn't selected in the end, his performance was leaked to the internet and has gained a cult following. The videos are available on the band's YouTube.
