Recorded at the Grote Kerk in Den Bosch as part of John Zorn's 70th birthday celebration at November Music in Den Bosch, this exciting performance pays tribute to one of Zorn's seminal influences - the 15th-century painter Hieronymus Bosch.

Performing on two different organs simultaneously, running from one to the other, this is one of the most bizarre installments in the entire Hermetic Organ series. The CD begins with a rare private performance of Zorn alone in the church exploring and stretching the organ's capabilities. For the evening performance, A Pilgrimage Through Hell, Zorn's dear friend and colleague of over thirty years John Medeski joins as his organ assistant, and the two of them literally pull out all the stops!
