I don't mind being lectured to. Here are some of my recent sources:
There's a trove of good mp3 stuff over at the Internet Archive's "
Naropa Poetry Archives" subsection, including scores of lectures by the prophet Alan Ginsberg.
Oxford University free podcastsGnostic Society lectures (good, though leans heavily to one school of thought)
Gnostic Radio (same caveat, different school)
Psychedelic Salon (MUCH besides entheogens, etc)
