Gradient Noise at ICMC 2026

I’m pleased to announce that I will be performing the world premiere of my piece Gradient Noise at the International Computer Music Conference (ICMC) in Hamburg, Germany on May 11 at 9:30pm. The following video except represent the work in progress. The final piece will be 10 minutes long and contain up to four layers of instruments with independent, corresponding, video objects.

Since 2019 I have been composing animated graphic scores for ensembles and soloists. Examples include Parking Ramp Project, SYNTAX, and Rhodonea. These generative works are projected for both the performers to read and audience to experience. I write software to generate and animate the geometric forms, and establish rules on how the forms are read, whilst allowing improvisation and the emotional response of the performer to play an integral part in each piece.

Gradient Noise, written using the Processing.org language, translates values generated by the Perlin noise algorithm into independent layers of seamless loops repeating at variable intervals. These loops are visualised as geometric forms, abstract visualizations, and evolving structures. The data generated is aleatoric, but the values can be tuned to range between slowly moving gradients or rapid, angular forms. When the sound and visuals are synchronized I respond not only to the animation but also to the changes in the timbre of my instruments.

Through Gradient Noise I am rethinking the relationships between musicians and machines. By translating the properties of n-dimensional Perlin noise into a musical language, the piece presents a unified ecosystem with coordinated timbres and geometric forms. Thus generating a living environment that requires active participation and improvisation. Ultimately, the work presents a contemporary model for computer music where the performer does not simply follow a score, but negotiates a path through a responsive, multi-sensory experience.

Anthony Cox, Suwal Singh, and John CS Keston at Berlin, Minneapolis

On May 15, 2025 I will be performing at Berlin, Minneapolis with world-renowned jazz/genre-spanning artist Anthony Cox and Suwal Singh on tabla for an evening of short solos and duets and a full-length trio set. For my part I will be playing the house Steinway though a modular skiff that I have setup to sample/resample and process the piano.

That skiff has changed slightly from what I’ve been using for the first few examples, but it is still yielding satisfying textures for me. More about the event is below or visit berlinmpls.com/calendar/cox-keston-singh. In addition a radio piece by Philip Nusbaum was aired on Jazz88 (KBEM 88.5), Minneapolis and archived here.

World-renowned jazz/genre-spanning artist Anthony Cox will team up with award-winning music technologist John C.S. Keston on piano/modular synth and Suwal Singh on tabla for an evening of discovery. Short solos and duets from the musicians will evolve into a full-length trio set of creative collaboration.

Anthony Cox is an internationally renowned arranger, composer, performer, recording artist, and educator. His career has spanned over 30 years of music education, composition, and performance, encompassing an extensive list of collaborations, performances, and recordings with notable artists in the field of jazz. The list includes Sam Rivers, Joe Lovano, Geri Allen, Kenny Wheeler, Ed Blackwell, Billy Higgins, John Scofield, The NDR Big Band, Dino Saluzzi, and Henry Threadgill.

John C.S. Keston’s background in music technology, software development, and improvisation leads him toward unconventional compositions that convey a spirit of discovery through the use of graphic scores, generative techniques, sound synthesis, experimental sound design, signal processing, and acoustic piano. Originally from the United Kingdom, he currently resides in Minneapolis, where he is a professor of digital media arts at the University of St. Thomas. He founded the sound design resource AudioCookbook.org, where you can learn more about his projects and performances.

Suwal Singh (tabla, guitar, sarangi) has contributed to the Minnesota music scene as part of projects such as SitarTabla (Eastern classical), Yeti Steady (avant-garde soundscapes), MoMoSauce (Nepali music), and Jest (pop rock). He has also worked as a session musician with Nathan Hanson, Brian Roessler, Eric Carranza, Colleen Buckman, and Dave Mehling and has appeared at Icehouse, the Varsity Theater, the Janet Wallace Fine Arts Center, Bedlam Theatre, St. Paul Art Crawl, AZ Gallery, KFAI, the Capri Theater, MN Yoga Conference, and Jazz Central Studios.

Sat. Sept. 9 Dosh and Keston with Tripfacesmile.com

Martin Dosh and I have been playing one-off shows together in various ensembles for longer than I care to divulge. However, unless I’m misremembering this will be the first time as a duet. The Rhodes electric piano has always been our common ground, and I will have my new Osmose Expressive E along as well to share how I have been approaching that instrument. Tripfacesmile.com will start the night off with a set of modular synthesis. Please join us at ROK Bar, 882 7th St. W, Suite 12, St. Paul, MN 55102 on September 9, 2023.

Friday, Sept. 1 with Eric Carranza, Matty Harris, and Jesse Whitney

Join us for a night of music at ROK Bar, 882 7th St. W, Suite 12, St. Paul, MN 55102 on September 1, 2023. Jesse Whitney starts off the evening with a solo electronic set, followed by two trio sets from Eric Carranza (guitars and electronics), Matty Harris (saxophones), and me (keys included my Osmose Expressive E).

Please enjoy this archive of the stream from ACB Live Volume 3 featuring Eric Carranza from April 18, 2023. Eric and I had a great time improvising together. I love Eric’s playing, his sense of sound design, and the way that he builds textures with electronics.
