Consonant Dissonance out July 27, 2026

I am releasing a solo, acoustic piano album titled Consonant Dissonance on Elektramusic Berlin on July 27, 2026. Among the original compositions are several electroacoustic pieces that process the piano through a modular synthesizer. For each of those the piano signals are handled in different ways. These include granular synthesis, looping, pitch shifting, reverse, analog filtering, delay, and reverberation, all modulated via a function generator, low frequency oscillators, and a sampling touch controller which I operated while playing the pieces.

The modular synth I used for the album. Ironically this was photographed at the venue Berlin in Minneapolis​.

The album was recorded at The University of St Thomas, Schoenecker Center, Audio Studio on a Kawai RX-3 grand piano. Gratitude goes out to my former student Alejandro Vega for engineering assistance, and Adam Krinsky for mixing and mastering consultation. Well before I recorded the album I performed the pieces live at a few venues including Berlin, the excellent music venue in Minneapolis that borrows the German city’s name. The irony isn’t lost on me that a label based in Berlin are the ones releasing it over a year later.

The videos above and below were made with a digital piano as a proof of concept for running piano through a modular system to process the signals. I had manipulated piano through processing at concerts in the past (see this article about an electroacoustic piano concert from 2016), but this was the first time doing it with a bespoke modular synth, where the modules and patching were specifically designed for that purpose.

Radical Futures Performance Piece: Rhodonea

On Wednesday, May 8, I debuted a performance piece titled Rhodonea at the Radical Futures conference at University College Cork, Ireland. At the concert I had the privilege of sharing the bill with Brian Bridges, Cárthach Ó Nuanáin, Robin Parmar, and Liz Quirke.

Rhodonea is a series of audiovisual etudes performed as a model of how we might collaborate with near future synthetic entities. Software feeds automated, algorithmic, projected visual cues, tempi, and low frequency oscillations to improvising electronic musicians. The compelling visuals, based on Maurer Roses, suggest melodic, harmonic, and percussive gestures that are modulated by data streaming from the generative animations. Throughout the piece artists adapt to the familiar yet unpredictable graphic scores and corresponding signals. The end result is an impression of how humans might interact with AI in a collaborative and experimental way.

I chose to perform Rhodonea as a soloist although it can be performed by an ensemble of up to four musicians. The generative and improvisational aspects mean that every performance is different than the next, but the piece has a consistent signature that leads the music. This includes modulation corresponding to each rhodonea that is translated into MIDI data and fed to parameters that effect the timbre and other aspects of the instruments. I captured the video above the day after the performance, which illustrates the characteristics of the piece, which I developed in Processing.org.

For this international performance I used four instruments inside Ableton Live 12 controlled by an Arturia KeyStep to minimize the gear I needed to travel with. The Ableton instruments I used were Drift, two instances of Meld (a macrosynth new in Live 12), and Collision. In the video below you can see how the generative graphics are manipulating the filter in Drift.

Bloodline: The Central Planes

November 8, 2021 marked the debut release from the trio Bloodline (Cody McKinney, Peter Hennig, and myself). The album was recorded in December, 2016 – a foreboding moment just before the world was plunged into the chaos of neo-nationalist politics. It took five years of sporadic listening, discussing, editing, mixing, and mastering to finally release it. Despite the delays, the music is just as relevant to me now as it was then.

Largely based on a series of graphic scores titled, Grocery List, by Cody McKinney The Central Planes is a raw, visceral, free, and exhilarating journey into the unknown. My endless gratitude goes out to Peter Henning and Cody McKinney for including me in this grand experiment, Steve Kaul for ingeniously engineering these weird sessions at Wild Sound Studio, Adam Krinsky for his tirelessly creative mixing, Huntley Miller for his expert mastering, and _you_ for daring to listen.

Bloodline is:
Peter Hennig (drums, cymbals, percussion, prepared piano)
John CS Keston (Rhodes, Piano, synth, electronics, prepared piano)
Cody McKinney (bass, vocals, electronics, various noisemakers, prepared piano)

Recorded at Wild Sound Studio, NE Minneapolis MN – December 2016
Engineered by Steve Kaul
Mixed at Bellows Studio, St Paul – Summer 2021
Mix Engineer – Adam Krinsky
Mastered by Huntly Miller at HM Mastering
Album art – John CS Keston

Parochial Dissonance by John C.S. Keston

Parochial Dissonance (Æther Sound, Dec. 4, 2020) – The title of this release describes the tragedy, loss, and suffering experienced when we narrow the scope of our worldviews. The album is a series of solo pieces captured from three streaming performances during the COVID-19 pandemic, and two live performances just before. Each piece was improvised within sets of rules applied to process, time, texture, and tonality. The pieces were performed on various synthesizers and Rhodes electric piano with occasional use of looping, arpeggiation, and signal processing. Continue reading for a look at the liner notes.

ISSTA 2019 Call for Proposals

October 31st and November 1st, 2019 the Irish Sound, Science and Technology Association annual conference and festival will be held in Cork, Ireland at CIT Cork School of Music. Keynotes include a performance and lecture from Robert Henke (Ableton Live, Monolake) and a performance and workshop from Ellen King (ELLLL / Gash Collective).

I starting going to ISSTA in 2017 and have had incredible experiences while attending and performing. It’s usually a fairly small gathering of like-minded artists, educators, performers, and scientists all of whom are experimenting with sound in fascinating ways. I’ve participated in many events, festivals and conferences, but nothing aligns better with my interests and practice than ISSTA does. If you appreciate the music and sound experiments I share here on ACB, then please review the call below for details about this wonderful gathering. Continue reading
