Initially started as a a solo project until Deacon D. was joined by guitarist Åskväder in September 1999. After an hiatus HETROERTZEN resurfaced in Sweden in 2009 with the release of 'Exaltation Of Wisdom' issued on their own imprint Lamech Records. That album put forward the band's early interest in the occult, Gnosticism and Illumination. 2016 saw the release of their critically acclaimed ' Uprising of the Fallen' previous album, HETROERTZEN are now releasing their brand new album entitled ' Phosphorus Vol 1' for a late Spring release on Listenable. HETROERTZEN comment about 'Phosphorus Vol 1' : " A new day has come to pass. A new ray pierces the veil of darkness and confusion. A new gem feeds the astonished sight and yet we walk through times of uncertainty before facing the switching Era... After five years of silence and lots of work, Hetroertzen finally give you the first Volume of 'Phosphorus', which is the crown for our latest Opus or the new Sephira in our artistic/spiritual development. This is in fact a strong title, taken from the Vampiric-eucharistic ritual of the "Ecclesia Gnosticae" (Gnostic Church) which inspired the "Libation" passage in the Order of the Knight Templars; and even in the Catholic Mass later on. "Unless You Eat the Flesh of the Son of Man and Drink His Blood You Have No Life In You" The Royal Art or the Dragon's Arts are present more or less in any occult teaching as Alchemy aims to conjoin separated ways into the quintessence of "Holy Marriage".
