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 of a freight train near downtown Minneapolis today using an old third generation 20 gig iPod running Linux (more info at ipodlinux.org). The microphone I used to capture the sound was an Audio Technica AT822 stereo condenser, list price of $419, but zZounds.com has them for about $250. The nice thing about the AT822 is that it comes with an XLR to 1/8″ stereo cable as well as a standard “Y” cable. This makes it easy to plug it into a hand held portable recording device like a DAT recorder or MiniDisc.
Unfortunately the iPod only records in mono via the headphone jack, but I was able to get a good strong signal into it via the left channel element, and record at a staggering 88.2kHz sampling rate! 96kHz is also supported. There is a way to get a stereo line level signal recorded through the dock connector, but I would need a preamp between the iPod and the mic so I may not bother unless I find something cheap, tiny and battery operated. I’ve ordered a replacement battery for the iPod, and I’m planning on keeping this small kit in my bike bag to make impromptu recordings. I would be interested in hearing about other examples of good quality field recording ACB readers have used. Anyone else have similar techniques?
To make this sound I increased the gain on some 60Hz buzz that I grabbed out of a bass guitar recording. There’s no bass, just the hum of electrical interference. A lot of boosting was necessary to get an adequate level.
Afterward I time stretched the waveform by varying amounts at consistent time intervals and manged to create this rhythmic pattern. A touch of chorus gave it some stereo spread and a short delay put it into space.
A lack of galactic space time has forced me to go backwards for the One Sound Every Day project, but I hope you’ll enjoy this track from Keston and Westdal’s latest release, One Day to Save All Life. Cover Your Eyes started out as a loop of sustained Rhodes notes that I had dropped into Ableton Live during a rehearsal for a show. If I remember correctly, we ended up performing the piece the same night that we created it. I love the samples Nils added that are destroyed with processing creating some complex and swirling textures throughout the piece.
I produced this sound by programming a scale in a MIDI clip and then sending it to a virtual instrument designed to allow for freely manipulating granular synthesis through several seven point envelopes. I made several takes while I adjusted the envelops and other parameters.
One warning, this take has some piercingly high frequencies in a few places. The sound reminds me of some sort of scrambled futuristic alarm system. This led me to adding a warehouse reverb to the mix to put in into sci-fi thriller territory.
With very little time for today’s sound I resorted to randomizing the parameters in Pluggo’s xmod synth, then resampling the results as I dragged the mouse up and down on the virtual keyboard in Ableton Live’s sequencer. I often use this technique with a variety of VSTs as a starting point to get a new sound, so I thought I’d lay it down, so you can hear a little behind-the-scenes audio.
