Early Experiments: Ebb and Flow (1998)
Ebb & Flow was a series of three performances streamed live over the web that explored the relationship of technology, sound, and biological processes. Conceptualized by web-artists Nina Sobell and Jesse Gilbert, Ebb and Flow consisted of weekly webcasts of electronic experiments carried out using musical instruments, electroencephalographic devices (EEG), MIDI, and video.
Drawing on Sobell’s experimentation with EEG feedback, which dates back to her residency at the VA Neuropsychology Lab, Sepulveda, CA in the early 1970s — Brainwave Drawing (1973) — the team used IBVA software to translate the brain wave data into sound, via a MIDI bridge. The sounds corresponded to the frequency and amplitude of the peak wave, creating a musical baseline that was accompanied by live musicians. The sounds were mixed live to form an ongoing soundscape, and transmitted to a live audience on the web. During all performances a live audio and video feed allowed the online audience to experience the process in real-time. Related: Brain Avatar.
