Recording in Slovenia during his 2019 residency at the Ljubljana Jazz Festival at the secular Gallus Hall, after Slovenian churches prevented his using their organs, accusing Zorn of believing in supernatural powers, this 8th volume of John Zorn's Hermetic Organ series finds Zorn playing the saxophone simultaneously with the organ, using his feet, hands and elbows.

John Zorn continues his recording series improvising on large church organs with these three improvisations from St. John the Divine in New York City, a meditative place of worship dedicated to the author of the Book of Revelations, as Zorn evolves three powerfully introspective works, the longest opening to "The Doors of Perception".

The 6th in John Zorn's "Hermetic Organ" series of real-time improvisations performed by Zorn himself, this volume paying tribute to the 19th century suspense and horror writer Edgar Allan Poe, as Zorn evokes Poe's enduring and chilling imagination using the organ's immense power and implicit sense of foreboding, stretching the limits of the organ.

During a week in April 2017 John Zorn travelled to Paris, where he performed several concerts including "The Interpretation of Dreams", presented an evening with guests, and performed solo on the organ at the Grande salle Pierre Boulez, the full concert of which is presented on this CD, along with 30 minutes of recordings made before the evening's concert.

Tzadik's new Spectrum series begins with the collaboration of 3 legendary NY performers--Wadada Leo Smith (trumpet); George Lewis (trombone); John Zorn (alto sax)--in 8 technically superb and joyfully unique compositions and collective improvisations.
