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.
On Tuesday, May 19 DKO is releasing Absinthe Referent, available on cassette (limited edition of 100) and digital download. Although Jon Davis, Graham O’Brien, and I have been performing as DKO since 2011 this is our debut album. We recorded it at Bellows Studio during a live, in-studio concert with an intimate audience of friends and family members.
Graham and I edited the album down to six tracks that we handed off to Adam Krinsky for mixing. Finally we had it mastered by Huntley Miller. Please listen to a preview track from the album titled S33LUgRUN. We will be performing to celebrate the release on May 20 at the Turf Club in St. Paul, Minnesota with Dosh and A Love Electric.
I am pleased to be participating in an exhibition of work by Jasio Stefanski at Print Gallery in Tokyo, Japan. Jasio is showing a variety of his work including two pieces that we collaborated on together fron the series Spectral Tablature. The first piece is Synthetic Skyline previously exhibited for the Audible Edge sound art exhibition at the Katherine Nash Gallery in Minneapolis. The second piece is a new work in the series titled Synthetic Transitions.
To create the work I started by composing a simple sequence of notes that speed up and then slow down. Jasio requested that we included diagonal lines in the piece so I used linear portamento on the Moog Sub 37 to create the “transitions” he was interested in seeing. The video shows the plotter rendering Jasio’s Reprise of the work shown/heard in the image/audio below.
Jasio’s Reprise is based on form and color values as opposed to acoustic accuracy. The visuals were composed to place emphasis on the “transitions” or portamento. The output visually reinterprets the angles informed by the gliding notes without connecting them in the composition. When sonified the plotted design singles out the portamento, isolating it from the context of the sustained frequencies.
A couple of months ago I spent about 18 hours over two days recording synthesizers for the upcoming Camp Dark album Nightmare in a Day. It was a blast and the music is gorgeous. I wrote in more detail about the project here. The latest video, edited by Adam Svec, is for the song Are You Hiding. This one ends with a long passage of Moog Sub 37 running through the Minifooger Delay as I twisted the Time and Feedback knobs.
Are You Hiding” is the second video in a series to promote the release of Camp Dark’s new album, Nightmare In A Day (Icehouse MPLS on Friday 5/15). The story was inspired by holiday trips back to South Dakota. The song navigates the trajectory of playing roles of earlier versions of you. This veneer eventually falls apart when the years become visible. A person can only hide in plain sight for so long before they are spotted. It’s an anthem of empathy for those who experience this distance between former and current selves. “Are You Hiding” features performances by Graham O’Brien, Adam Svec, Dan Choma, Matt Leavitt, Matt Friesen, and John Keston.
Part music, part visual art, and part sound design, the collaborative series Spectral Tablature is something I’ve been doing in various forms since 2013. Recently I have been working on a new piece in collaboration with Jasio Stefanski for an upcoming exhibition of his work. I’ll share more information about the exhibit in a future post. For now I’d like to present some of the content that I generated in the process of working on the project.
The image above is spectral analysis of a piece of music that I composed deliberately to produce interesting sonic and visual forms. The piece includes three layers of sequences that slowly speed up and vary in pitch and then slow down again. The speed of the sequence was based on an LFO with a variable rate rather than BPM. This process, along with other techniques, resulted in a form that starts simple, approaches entropy, and then returns to its original simplicity.
The final piece will be reprocessed visually through a set of design criteria determined by Jasio. Once the new design has been printed I will digitize the image and reprocess it as sound. The new audio will retain the original frequencies and temporal information but the textural and timbral qualities will be completely transformed.
My duet project Ostracon will be performing this Thursday, February 19, 2015 for the first time since August. This time around I have prepared eight new compositions using the Elektron Analog Four and the Moog Sub 37. This track is an excerpt from a recording that I made during preparations for the show which will be held at the historic Lee’s Liquor Lounge music venue in Downtown Minneapolis.
