Radical Futures Performance Piece: Rhodonea

On Wednesday, May 8, I debuted a performance piece titled Rhodonea at the Radical Futures conference at University College Cork, Ireland. At the concert I had the privilege of sharing the bill with Brian Bridges, Cárthach Ó Nuanáin, Robin Parmar, and Liz Quirke.

Rhodonea is a series of audiovisual etudes performed as a model of how we might collaborate with near future synthetic entities. Software feeds automated, algorithmic, projected visual cues, tempi, and low frequency oscillations to improvising electronic musicians. The compelling visuals, based on Maurer Roses, suggest melodic, harmonic, and percussive gestures that are modulated by data streaming from the generative animations. Throughout the piece artists adapt to the familiar yet unpredictable graphic scores and corresponding signals. The end result is an impression of how humans might interact with AI in a collaborative and experimental way.

I chose to perform Rhodonea as a soloist although it can be performed by an ensemble of up to four musicians. The generative and improvisational aspects mean that every performance is different than the next, but the piece has a consistent signature that leads the music. This includes modulation corresponding to each rhodonea that is translated into MIDI data and fed to parameters that effect the timbre and other aspects of the instruments. I captured the video above the day after the performance, which illustrates the characteristics of the piece, which I developed in Processing.org.

For this international performance I used four instruments inside Ableton Live 12 controlled by an Arturia KeyStep to minimize the gear I needed to travel with. The Ableton instruments I used were Drift, two instances of Meld (a macrosynth new in Live 12), and Collision. In the video below you can see how the generative graphics are manipulating the filter in Drift.

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.
