One is Listen was an audiovisual piece that investigated the dynamic extremes of our perceptions, from the subtle, almost imperceptible, to the extremely loud, powerful and assertive. Not only was the auditory sense tested, there was a visual aspect to the composition, where 100 small, specially made LED lamps paralleled the auditory expression. This created a multi-sensory connection that flooded the senses. The visual aspect consisted of a string of LED lamps that followed the musical development, through a custom-designed computer program. One Is Listen lasted for 18 minutes, and was presented in the panoramic cinema at CAVI.
