Kazuhisa Uchihashi + UA

Playing a space like an instrument –
A fusion of live performance and installation

Kazuhisa Uchihashi, primarily known for his improvised guitar playing, has been operating on a global scale collaborating with artists from various fields. His partner for this collaboration was UA, who has built herself a broad fan base with her uniquely expressive singing style. The result was an experimental concert piece that blends elements of live performance and interactive installation.
The improvised performances of UA on vocals and Uchihashi on the guitar interactively trigger lighting and imagery, to create a dynamically yet delicately transforming audio-visual environment. While tracing lights and sounds, the audience could enjoy a novel kind of sensual experience in which the boundary between visual and auditory perception had vanished.

Sight and hearing act in concert to create a new spatial experience

23 speakers and more than 80 LED lights are arranged in an encompassing fashion around the stage, while a screen for video projections is mounted to the ceiling. The ad lib generated sounds of UA's singing and Uchihashi's guitar and daxophone playing are analyzed via a computer, and translated into abstract images and variously colored lights that transform the entire venue into an interactively changing space.

An originally developed interface for controlling the audio image's motion is installed at the position on stage at which Uchihashi performs. The operation screen shows the stage and marks indicating the speakers. When touching the screen with a pen, a circle forms around that point, and the performed sounds are audible at different volumes according to the circle's shading only from the speakers located within the scope of that circle. The performer can adjust the size of the circle - and thus the audio playback range - by changing the writing pressure, or draw multiple circles to produce various configurations for the motion and distribution of sound. Additionally, the device includes a looped playback function enabled by recording the pen's trajectory, and other functions that can be assigned randomly within a particular area.
