Secret Sound is a podcast focusing on the esoteric history of American music, from the 18th century to the present. For the last 15 years host Matt Marble has been researching marginalized American artists and the spiritual, often esoteric, influences that have empowered their work. From psychic pianists to prophetic instrument-makers, these artists found inspiration from within and often musically expressed themselves in experimental and imaginative ways. 

Each episode focuses on a single artist, and explores their biography, creative process, musical works, and influences. Along the way, listeners are introduced to diverse esoteric traditions, such as Theosophy, spiritualism, New Thought, Kabbalah, Enochian Magic, Vajrayana Buddhism, and more. We’ll also explore aspects of American history and society as broader contexts to individual artists and their work.

All episodes are free to stream or download. Also available on iTunes and Spotify.
