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.
