Originally from Luleå, a small town in the north of Sweden, Ahriman developed an interest in music from a very young age. Hailing from a somewhat musical family, he cited his grandmother, mother and younger sister as influences and he started songwriting himself between 1989 and 1990.[2]
Harbouring interests for Satanism (ostensibly that of the LaVeyan variant) and extreme metal as a teenager, he was introverted in his environment. When he was eighteen years old, he left for Stockholm, home to extreme metal acts such as Entombed and Dismember, whom Ahriman already knew personally.[2]
He has also been an active participant in death metal. Before he played in Dark Funeral he played in a blackened death metal band called Satan's Disciples, and he has a side-project called Wolfen Society, who released an MCD "Conquer Divine" in 2001, although difficulties with No Fashion Records hindered its success.
Ahriman and other Dark Funeral members were forced to have side-jobs after No Fashion did not grant them royalties for their work on Dark Funeral's backcatalogue. Consequently Dark Funeral filed suit against No Fashion, and have since spearheaded a campaign against "corrupt" record labels.[2] In October 2008, it was announced that Ahriman and Emperor Magus Caligula succeeded in obtaining the rights to Dark Funeral's entire backcatalogue.
In 2013, Ahriman and Dark Funeral signed to Century Media Records for their upcoming new studio album.
