This piece was presented in a live performance at EMS 2011 in New York City. The audio is based on hydrophone recordings of waves washing on Duxbury Beach in Duxbury, MA, USA. The portion you see in the example presented here is an excerpt of a pre-recorded audio-video piece, which accompanied with additional live audio based on the same hydrophone recordings.
I wanted to create a video piece that reacted directly to the cyclical events of the waves heard in the hydrophone recording. I wanted to visual part of the piece to represent the rising and falling intensities of the wave events, as well as the complexity of their sound.
The visual music for this piece, as well as the other two examples, was created using VDMX, a modular platform for live video performance developed for Macintosh OS X by Vidvox. VDMX is capable of taking audio input, analyzing the frequency and intensity content of that input in real-time, and generating control data from the intensity levels of several user-determined frequency bands.
I chose to analyze 4 frequency bands for each piece (different bands for each piece), and to coordinate the resulting control data to the red (R), green (G), blue (B), and Alpha channels of a gradient video synthesizer built into VDMX. I also applied delays to the R/G/B/Alpha channels to slow their rate of change somewhat, so their changes would be rendered more visibly, if less accurately. My intentions were inspired by data visualization, though the works are not intended to be a strictly accurate representation.
For Chris Marker is a combination of two other areas of my work, both built on memory and forgetting: an electroacoustic composition called "Prequel (2008)," and more recent work with video looping and color manipulation. I dedicated the resulting work to Chris Marker, for his investigations of the experiences of memory.
All the sounds were derived from "Rapproachement" (1994) for solo piano. The video created using VDMX.
Mike Bullock and Linda Aubry Bullock's "Lanalog" was a six-hour performance and broadcast event on WGXC 90.7 FM, taking place on 8 August 2015 and originating at Wave Farm in Acra, NY. Lanalog used FM, AM, and natural acoustic to connect performers and video projections located around the Wave Farm buildings and property. The piece explores interference, feedback, and contingency of site; confronts the uneasy relationship of signal to noise in the rural airwaves; and addresses our fading memories of analog television and the uncertain future of analog radio.
