In this week's episode Christopher Hill speaks with Joanna about: psychedelics, music and ecstatic change; the spread of esoteric, spiritual knowledge through the music of the sixties; the mysterious spiritual revolution of the troubadours; Walt Whitman, Emerson and the American, progressive ecstatic tradition; the Beatles and the English visionary culture of nature mysticism; "Hey Joe" and the call to the West; Kennedy's assasination and its effect in Bob Dylan's music; a broader sense of history about social transformation; the visionary river of collective consciousness; the double vision of art.
