Video: Rhodonea II at SEAMUS

Posted on March 25, 2025 by John C.S. Keston

This video is a new interpretation of Rhodonea (Rhodonea II) that I performed for SEAMUS (the Society for Electroacoustic Music in the US) at Purdue University on Saturday, March 22, 2025. Attending and performing at the conference was a fantastic experience. I’ll share more about the event in future post.

The animated, generative, graphic score developed with Processing.org sends corresponding MIDI data to one of my favorite electronic instruments of late, the Dirtywave M8. Previously I performed the piece in Ireland at the inaugural Radical Futures conference.

The piece serves 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 visuals, based on Maurer Roses, suggest melodic, harmonic, and percussive gestures that are modulated by data streaming from the generative animations. Throughout the piece the artist adapts to the familiar yet unpredictable graphic scores and corresponding signals.

Note: please watch in full screen with the lights off and listen on headphones or high fidelity stereo speakers

Audiovisual Collaboration: The Dark at the End of the Tunnel

Posted on October 17, 2023 by John C.S. Keston

This is the last in a series of live audiovisual collaborations with Chris LeBlanc and Shawna Lee. The performance was captured at at the Lakely in the Oxbow Hotel, Eau Claire, Wisconsin (https://www.theoxbowhotel.com/lakely/) on September 30, 2023.

Chris LeBlanc and Shawna Lee produced live visuals using their integrated, modular video synthesis systems as I performed. This piece titled, Dark at the End of the Tunnel, is an electro-acoustic piano composition. In this adaptation I used a a stage piano, but the processing and accompaniment are as they would be if the piece were performed on an acoustic instrument.

Audiovisual Collaboration: Chris LeBLanc & Shawna Lee, Part 2

Chris and Shawna produced live visuals using their integrated, modular video synthesis systems as I performed. This as yet untitled piece is driven by morphing drums and sequences on the Dirtywave M8 tracker. I also improvised parts on the Osmose Expressive E and the Numa X Piano GT.

Audiovisual Granular Synthesis of Water Objects

Posted on June 19, 2014 by John C.S. Keston

This is a screen capture from a Max project I developed that does interactive, synchronized, granular synthesis of corresponding sound and video that’s tentatively titled AVGM for Audiovisual Grain Machine. I have used the software during aperformance at the Echofluxx festival in Prague and at the Katherine E. Nash gallery for the opening of The Audible Edge exhibition during Northern Spark 2014.
