Six-and-a-half hours of the 1989 weekend Terence McKenna shared with Amazon explorer and medicinal-plant researcher Nicole Maxwell. Sound Photosynthesis sold the full event as a seven-and-a-half-hour set (5 audio cassettes #A478-89 / 4 video cassettes #V192-89) under the title "Shamanology of the Amazon"; this collection previously held only a one-hour video excerpt of it. McKenna opens by noting "last year I was here with Riane Eisler", which places this at the Ojai Foundation the year after that 1988 weekend. Maxwell is audible throughout, trading Amazonian pharmacopoeia -- contraceptives, abortifacients, plant taxonomy -- against McKenna's overview of shamanism and the ecological crisis.

Two-part Esalen lecture from August 1992. Nominally on politics and ethos, it ranges over psychedelic ontologies, modernity, language, reason, religion and freedom in part one, then shamanism, synesthesia, paranormal phenomena, climatology, astronomy, Renaissance humanism and telepathy in part two. Released from Esalen's own archive.

A long-form Terence McKenna talk on matter, magic and the alchemical imagination, running just over four hours.

Complete twelve-tape participant recording of Terence McKenna's multi-day Esalen workshop on the I Ching, the Tao and the Timewave -- roughly fifteen hours of unedited sessions. Circulated as a participant tape set; the source upload dates it to November 1988 while the Terence McKenna Archives bibliography lists a 1991 Esalen workshop under the title "The Time Wave, the Tao, and Novelty".
