In 1989, Flowers was expelled from the Odinic Rite following his Open Letter to the Leadership of the Asatru/Odinist/Troth Movement wherein he detailed his involvement with the Temple of Set.
He has recently contributed an article entitled Three Decades of the Ásatrú Revival in America to Tyr, a periodical espousing Radical Traditionalism.
Sveinbjörn can be heard performing Ásatrú marriage rites for Genesis and Paula P-Orridge (now Alaura O'Dell) on Psychic TV's LP Live in Reykjavik and on the double LP entitled Those who do not.
