Chaos Magick, composer John Zorn's quartet with Brian Marsella on Fender Rhodes, piano & Mellotron, John Medeski on organ, Kenny Grohowski on drums and Matt Hollenberg on guitar, merge contemporary classical with jazz, funk, rock, blues, film soundtrack, and noise improvisation on a journey of 9 compositional Cantos into Orpheus' ninth concentric Circle of Hell.

The Simulacrum trio of John Medeski on organ, Kenny Grohowski on drums and Matt Hollenberg on guitar, with prior releases Inferno, Unspeakable Depravity..., Beyond Good And Evil and Baphomet, continue composer John Zorn's investigation on the dark side of swinging jazz merged with rock & compositional attitudes, as he explores the written works of Antonin Artaud.

"Chaos Magick" is a contemporary magical practice based on the ideas of Austin Osman Spare, influencing the work of William Burroughs, Robert Anton Wilson, and Aleister Crowley, and here inspiring the compositions of John Zorn for his Simulacrum ensemble of Kenny Grohowski on drums & percussion, Matt Hollenberg on electric guitar, Brian Marsella on electric piano and John Medeski on organ.

The eight album from John Zorn's Simulacrum ensemble, blurring the lines between improvisation, fusion, exotica, compositional forms, and death-metal organ trio, performed with keyboardist John Medeski and members of heavy rock bands Cleric and Imperial Triumphant--Kenny Grohowski & Matt Hollenberg--in an epic 40 minutes long-form composition.

The 3rd release of saxophonist Igor Lumpert's Innertextures, expanded to a quartet with the Chicago saxophonist Greg Ward joining the previous trio of Chris Tordini on double bass, and now with Kenny Grohowski on drums, with trumpeter Jonathan Finlayson joining on two tracks and bass clarinetist John Ellis on another, all performing Lumpert's exuberant and clever compositions.

The second release by Zorn's heavy new organ trio Simulacrum of John Medeski, Matt Hollenberg and Kenny Grohowski with guests Mark Ribot on guitar and Trevor Dunn on bass, three generations of musical explorers coming together to rip your mind to shreds.
