I have come across a reference to an audio recording that was available online around 2005. This recording that was made available for download included information by or from Simon, the editor of the Necronomicon. If anyone has any leads on this I would be grateful.
EDIT: On the sacred-magick.org download library I did find some audio materials purported to be audios by Simon. I procured them. However if anyone has further information from other sources I would still appreciate that, as I would like to compare them.
