For episode 10 of Pop Apocalypse, we welcome the musician, composer, and producer Trey Spruance. We discuss Trey’s early musical and occult explorations and how reading the philosopher Henry Corbin changed the course of his life. Trey then takes us through the esoteric dimensions of Secret Chiefs 3 and how albums like Book M and Book of Horizons are filled with correspondences to Kabbalah, astrology, Hermetic magic, and Pythagorean musicology. Along the way, we touch on Trey’s work with Jim Zorn and Kronos Quartet, his conversion to Eastern Orthodox Christianity, and the afterlives of Saint Cyprian the Mage.
