So imagine my surprise when I put on his new CD—Both/And (Sunnyside). The album is a magnificent work that combines acoustic improvisation with densely layered electronica and sound sampling. It's a delicate feeding frenzy of jazz forms and computerized expressions that simultaneously astonish and tickle. This is Denny working on a massive canvass, exploring his orchestral ambitions without bearing the brunt of hirign space and hundreds of musicians. His ability to colorize with cinematic flourish and create regal and suspenseful moods by dense-packing acoustic and electronic forms gives jazz a new, liquid-neon dimension.
What's extraordinary is that Denny selected, created and integrated all of the sounds and instruments himself. At times it sounds as if there are dozens of musicians playing. As I've written about Robert Glasper, RJ & the Assignment and José James, the future of jazz is incredibly exciting if you think in terms of digital collage and textures mingling with acoustic instruments. Denny's work resides in the same space—where sound samples, software and instruments become electronic tubes of paint and the size and scope of what's created is large, provocative and breathtaking. You have to hand it to Denny for continuing to let curiosity run his musical kitchen and for pushing himself to explore the outter edges of the electronic galaxy.
Last week, I spoke with Denny, 75, about his new album...
JazzWax: Your new album is such a radical departure from the acoustic recordings you've made in recent years. What was the motivation?
Denny Zeitlin: Even though I've been immersed in acoustic music over the past several decades, I've been keeping an eye and ear on developments in electronic music. Since 2000, there have been big technological improvements that make it possible for musicians to create multi-layered music in real time. You can draw on vastly improved and expanded sources of sound and more effortlessly record, edit and mix performances.
DZ: Almost. I found many of these technological improvements hard to resist, so I began to revisit electronic music—upgrading my studio to build on what I had created from 1968 to 1978, when I explored the electro-acoustic integration of jazz, classical, funk and the avant-garde.
DZ: Expansion  and Syzygy  were recorded at 1750 Arch Records' studio in Berkeley, Calif. on an 8-track Ampex tape recorder. In addition to all my keyboards and synths, I had George Marsh on drums and percussion, and either Mel Graves or Ratzo Harris on acoustic and electric bass.
DZ: Absolutely. Back then, finding space on tape for overdubbing after basic tracks were laid down was very challenging. The process often involved shared tracks and gymnastic moves to punch in and out to avoid erasing something crucial on the same track. Mixing also was arduous—frequently with three sets of hands on the console to make all the adjustments in real time. By the time of my electro-acoustic-symphonic score for the remake of Invasion of the Body Snatchers (1978), mixing consoles had some programmable features, and tape machines had 24 tracks, but the real leap forward was years down the road.
DZ: The advent of digital audio recording software in the 1990s dramatically changed everything. I used Pro-Tools for Both/And and never ran into a significant problem of space or tracks for overdubbing. For example, there is a section of Monk-y Business Revisited that involves over 60 tracks playing simultaneously. Overdubbing is technically a breeze, and the possibilities of editing have vastly expanded. And automation is available for mixing, so the days of dancing around colleagues at the console are over.
DZ: In some cases. For example, on Monk-y Business Revisited—which has numerous written sections and complex meticulous orchestration—improvisation remained the centerpiece, as it does throughout the whole album.
JW: And yet the electronic feel dominates.
DZ: Multiple keyboards trigger a host of sound sources, and an array of pedals alter these sounds, I felt like a galactic orchestra playing in real time. For example, in the case of Meteorology, 90% of the piece emerged from a single free improvisation. In other instances, a seed for a new piece might emerge—from a programmatic idea or basic theme or a pattern, a collision of unusual textures, or a sound that grabbed me as I started to improvise. In this case, it's a work in motion, collaging as I moved forward.
DZ: Yes, in some ways it was more like that process. Since I was free from the limitations of live concert performance, I had the opportunity to review, overdub, delete, add sections before and after, and gradually bring a finished sound painting" to life.
DZ: As I mentioned, Pro-Tools was my digital audio workstation. But I also used DVZ Strings by Audio Impressions, a relative newcomer on the scene that's magically powerful but complex and challenging to install, maintain and use with sophistication. I also used Omnisphere and Trilian from Spectrasonics, which provide high-quality software synths and huge libraries of sounds and sound-altering capabilities that are more user-friendly. Sample libraries have greatly improved, and I used a number of them, including Vienna Symphony Orchestra and BFD.
DZ: I used a Yamaha S-90, which is an excellent hardware synth and keyboard trigger with an extensive sound library and breath control capability. I love the keyboard feel, which is also present on the three Yamaha CP-33 keyboards I used to trigger the various synths and libraries.
DZ: I wouldn't say there were main inspirations. This project drew on all the important musical experiences of my life—the composers and performers, regardless of genre, who have touched me most deeply. I hoped my compositions and performances would emerge as a broad and deep exploration and integration of electro-acoustic possibilities.
DZ: With my focus on improvisation, I spent most of my time trusting that something meaningful would happen and trying to avoid conscious manipulation. I find this ecstatic state very precious. Then there were the many opportunities to play back the music and reflect. I might feel something else was needed. It might be obvious, or require a musical search that could be tedious or exciting. And the search might lead to new ideas and a new piece.
JW: Did pieces turn out as you originally expected?
DZ: The process was mixed. Hearing a composition approach what I had in mind was exhilarating. Yet there were times when I would decide a whole section of music simply didn't make it and would have to be deleted. For me, the gamut of human emotions is expressed on this CD, and the act of mixing and mastering—though trying at times—infused me with these feelings as I attempted to maximize their communication. When I listen back, I find myself forgetting that I played all the parts.
