I'm looking for links or directions to audio files which are similar to these:

http://www.youtube.com/watch?v=Wmgtc1mVUdc

Preferably similar in the style of presentation, i.e. authentic instructions and demonstrations of rituals, not simply discussions about occultism, etc. Any area of occultism will do, not just Thelemic.

The older the better.
