Merging heavy melodic jazz with tinges of heavy metal, John Zorn's Simulacrum trio of John Medeski on organ, Kenny Grohowski on drums, and Matt Hollenberg on guitar perform nine of Zorn's intense compositions in a beautifully recorded concert at the Firehouse 12 studio, the band's consummate playing and passion bringing power to Zorn's darkly exciting music.

John Zorn composes for, conducts and plays saxophone with his Simulacrum group with Kenny Grohowski on drums, Matt Hollenberg on guitar and John Medeski on organ & electric piano, a scorching band that combines Downtown NY jazz and metal forms as they explore the life and thoughts of Dutch 17th century Age of Enlightenment philosopher Baruch Spinoza.
