“The abridged Black Mass (from the Satanic Rituals by [Anton] LaVey) will take place,” he said. “Then The Choke [a local band] will perform. After that, Matthew Garman will have a Satanic (Ahrimanic) Exorcism done [which purports to remove the Holy Spirit from him]. Kelsey [Daniels] and I will be presiding over this rite. Before each ritual I will lecture on the purpose and point of each ritual as it pertains to the Ahrimanic [Satanic] Faith.”
