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.
I made this recording half way across the Central Avenue bridge from Northeast Minneapolis, to the downtown area. This bridge crosses the Mississippi, which was virtually frozen over except for water flowing rapidly over stages of a lock and dam system.
Huge formations of ice were hanging over the falls collecting on logs caught in the flow. The stereo image of the recording consists of the raging river below on the left hand side and sparse traffic on the right. I used the built in mics on the PCM-D50 covered up with a nice fuzzy wind screen like a winter hat.
While working in the studio recently I plugged in a cable from an auxiliary send to record some bass and got some horrible feedback. So horrible that I was determined to record it. The reason I was getting the feedback was because the same send that I was using to record the bass happened to be turned up on the channel that I was using to monitor the signal. I realized this immediately, but the sound was quite interesting due to the subtle latency on the signal path caused by the digital hardware involved. Here’s a couple of layers of the feedback running through reverb. I also made adjustments to the pitch a time stretched the recording in a few places.
I recently recorded a few passages of clavinet on a piece I’ve been working on for a while. My Hohner E7 is still in disrepair, so I had to rely on a sampled version of the instrument. I processed the sampled version in a similar way to how I would have processed the real thing.
Generally I tend to try new things rather than rely on previous settings and techniques, however, I almost always starts with compression on the clav. This time, I followed the compression with amp modeling, chorus, and reverb. The context is the key to what kind of processing I’ll use on this versatile instrument.
A few years ago I created a technique for live looping in Ableton Live. I wanted to record and stop recording a clip in the session view without using a bulky MIDI foot controller. So, I came up with the idea of modding a mouse by connecting a simple sustain pedal into the left button. This way I could keep playing my instrument with both hands and record to any clip that the mouse cursor was resting on.
I found that I could do lots of other things while continuing to play two handed, like start a scene, stop a clip, mute a track, etc. Usually I reserve setting up my modded mouse for shows, but it’s a very useful tool in the studio for capturing two handed keyboard parts, like the Rhodes in this segment from a new track.
