About John CS Keston

John CS Keston is an award winning transdisciplinary artist reimagining how music, video art, and computer science intersect. His work both questions and embraces his backgrounds in music technology, software development, and improvisation leading him toward unconventional compositions that convey a spirit of discovery and exploration through the use of graphic scores, chance and generative techniques, analog and digital synthesis, experimental sound design, signal processing, and acoustic piano. Performers are empowered to use their phonomnesis, or sonic imaginations, while contributing to his collaborative work. Originally from the United Kingdom, John currently resides in Minneapolis, Minnesota 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 will find articles and documentation about his projects and research. John has spoken, performed, or exhibited original work at New Interfaces for Musical Expression (NIME 2022), the International Computer Music Conference (ICMC 2022), the International Digital Media Arts Conference (iDMAa 2022), International Sound in Science Technology and the Arts (ISSTA 2017-2019), Northern Spark (2011-2017), the Weisman Art Museum, the Montreal Jazz Festival, the Walker Art Center, the Minnesota Institute of Art, the Eyeo Festival, INST-INT, Echofluxx (Prague), and Moogfest. He produced and performed in the piece Instant Cinema: Teleportation Platform X, a featured project at Northern Spark 2013. He composed and performed the music for In Habit: Life in Patterns (2012) and Words to Dead Lips (2011) in collaboration with the dance company Aniccha Arts. In 2017 he was commissioned by the Walker Art Center to compose music for former Merce Cunningham dancers during the Common Time performance series. His music appears in The Jeffrey Dahmer Files (2012) and he composed the music for the short Familiar Pavement (2015). He has appeared on more than a dozen albums including two solo albums on UnearthedMusic.com.

Live MIDI Sequencing Using Pyramid from Squarp

Posted on February 24, 2016 by John CS Keston

Last July I wrote an article titled, How Do You Do Your Live MIDI Sequencing? In the article I expressed my frustration with the ubiquity of step sequencers and lack of modern hardware sequencers that handle live recording and polyphony. In December, 2015 I became one of the lucky few to own a Pyramid sequencer by Squarp. Pyramid is an amazing instrument that does everything that has been lacking from most modern sequencers, plus an ever widening array of advanced features available as MIDI effects. It’s hard to contain my excitement about this machine! Squarp has been extremely communicative with their customers through email and their online forum. New releases have been frequent during its life cycle, and I expect many fantastic new features and advancements in the near future. Here’s a few of Pyramid’s current capabilities that I find exciting:

1. Live recording of polyphonic notes with velocity, pitch bend, channel pressure, mod wheel, and continuous controllers. Notes are recorded without quantization unless the Quantizer MIDI effect is applied to the track. What makes this exciting is that although polyphonic and un-quantized recording is common in software it’s rare in new hardware sequencers.

2. Simultaneous track lengths and time signatures are independent of each other. The track lengths are not limited to bars, but can be adjusted down to individual steps. For example, a five bar and three step phrase is possible. This feature allows for polyrhythmic sequencing which I’m very excited about.

3. Pyramid projects are saved on a standard removable SD card as a collection of MIDI files. Although there are plenty of editing features in Pyramid, if you need to for any reason, the files can be edited on a computer in your favorite DAW. You can also create or import MIDI files from elsewhere into a Pyramid project!

I’ll share some of the music I’ve been creating with this beast soon. I could (and will in future posts) go on about euclidean rhythms, step editing, sequencing tracks, chaining sequences, and CV/GATE i/o – all capabilities that Pyramid has, but for now take a look at this collection of tutorial videos that Squarp shared just yesterday:

Ostracon and Chris LeBlanc Featured at #L2L, Feb 10, 2016

Posted on January 25, 2016 by John CS Keston

My eletroacoustic duet, Ostracon in collaboration with Graham O’Brien on drums, is performing at the Landmark to Lowertown series hosted by the American Composers Forum. Chris LeBlanc will be joining us with his modular, analog, video synthesis system running through a wall of vintage 22″ CRT monitors. Our performance starts at noon at the Bedlam Theatre in St. Paul.

The Forum is pleased to announce its second season of Landmark to Lowertown, a program where new music sees the light of day in downtown St. Paul. In starting a new tradition, this season’s composer/performers are awardees of the Minnesota Emerging Composer Award (MECA) from ACF and generously funded by the Jerome Foundation, an award that highlights artists in Jazz/Improvisation, Electronic, and World music.

Ostracon is in the process of finishing our 2nd album. There’s no scheduled release date as of yet, but the recordings have been made and editing is underway. Expect more announcements about the album within the next couple of months. For now we will be pleased to see you at the Bedlam on February 10, 2016!

Video: 70 Crowdsourced Scores Performed in 9 Hours

Posted on January 4, 2016 by John CS Keston

On June 13, 2015 I collaborated with a team of nine students and nine musicians on a project I directed for Northern Spark, an annual, all-night, art festival In Minneapolis and St. Paul, Minnesota. We titled the project, Instant Composer: Mad-libbed Music and the intent was to engage the audience into instantly writing musical compositions for an ensemble of improvising musicians.

I discussed the concept here in-depth and also announced the project last June. I had no idea what to expect, but was thrilled with the outcome. Around 115 crowdsourced scores were entered into a database via our mobile application. During the nine hour performance we interpreted nearly 70 of those pieces for the audience.

This video should give you a sense of what went on that night, but no media can fully represent an event like this. I can say that it wouldn’t have happened without the student collaborators, our collective of excellent musicians, the Northern Spark organizers, Art Institutes Minnesota, and the hundreds of people in our audience willing to engage in the process. Please see the video for the full project credits.

Taming of the CPU 3.0 Venue / Date Change

UPDATE: The Nicollet is going to be under construction on January 7, 2016. Currently they are trying to find us an alternative venue, or if that fails a later date. I will update this post when we know more. Sorry for the inconvenience! Continue reading →

The First Annual Rhodes Summit

Posted on December 6, 2015 by John CS Keston

It’s no secret that one of my preferred instruments is the Rhodes electric piano, which is why I am very excited to be one of four Rhodes players for the first annual Minneapolis Rhodes Summit at the Icehouse, 2528 Nicollet Ave, Minneapolis, Minnesota 55404. This concert is happening tomorrow night (Monday, December 7, 2015 at 9:00pm) as part of JT’s Jazz Implosion. JT Bates will be joining us on drums for the second set. So who is us? We are four keyboardists belonging to the Twin Cities scene including, Martin Dosh, deVon dVRG Gray, John Keston (that’s me), and Bryan Nichols. The four of us are known for playing Rhodes electric pianos either frequently, or most of the time. What does it sound like when four Rhodes players go at it all at once? I have no bloody idea, but I’m looking forward to finding out! Please join us for this experiment in Rhodes overload. $8.00.
