Past Exhibit › Gregory Shakar: MoodVectors

An exhibition of interactive audio sculptures and expressive electronic art.

Archived on August 25th 2007.

Gregory Shakar creates interactive audio sculptures and immersive environments. As an artist and musician he is devoted to the creation of emotive and expressive electronic art. Viewers participating in his interactive installations encounter melodic bolts of lightning, giant sonorous metronomes, and enormous undulating pixels. His performance work includes audience participatory symphonies performed on hundreds of mobile phones and music for quasi-harmonic audio-visual environments.

Shakar’s work has been exhibited internationally including at Ars Electronica (Linz, Austria), Digital Arts Festival (Tokyo, Japan), Nagoya City Museum of Art (Nagoya, Japan), Sonar Festival (Barcelona, Spain), the London Institute for Contemporary Art (London, UK), the Smithsonian Museum of American History (Washington, D.C), Lincoln Center’s Avery Fisher Hall (New York) and The Kitchen (New York).

We are pleased to present the first survey of the artist’s work in an exhibition entitled “MoodVectors”.

In The Storefront:

Wood Urchin
Wood Urchin is a musical sculpture that responds to the bending of its antennae. Two of the antennas are used to form the bass and tenor notes of a musical melody. A third adjusts the time intervals between notes (for rhythm control) and the last affects a timbral change to the sound allowing for musical emphasis.

Red Urchin
Red Urchin is a musical sculpture that is played by placing your hands near any of its four antennas. The flexible antennas can be positioned in different configurations – adjusting to personal preference, allowing for multiple players, or even enabling it to respond to its environment without direct influence from a participant. The antennas are sensitive to changes in distance from your hand. One antenna controls the pitch of bass notes another controls tenor notes. The other two antennas alter the timbre of the sound being produced, each in a different way.

In The Gallery:

The Analog Color Field Computer
The Analog Color Field Computer (ACFC) is an interactive video and sound installation that makes both minimal and maximal use of computer monitors. Exhibitions of the piece employ a suite of sculptural computers whose custom electronics drive standard video displays and loudspeakers. Instead of presenting complex images (like computer graphics or photographs) each ACFC unit repurposes its monitor such that at any one time a solid field of color is spread across its entire display surface. Likewise with sound, instead of producing complex timbres each unit produces a pure sine tone. The sculptures’ colors and tones surge in steady pulses, conveying sonic textures and luminescent patterns into the sparsely lit exhibition space.

The Lightning Organ
The Lightning Organ is a musical sculpture that produces sound by governing the audible pitches of visible electric sparks. Conventionally, electronic musical instruments employ loudspeakers to convert electrical audio signals into acoustic sounds. A loudspeaker uses electricity to push and pull a speaker-cone which in turn imparts vibrations into the air. In contrast, The Lightning Organ impels sound directly into the air by emitting “tuned” electricity unmediated by any mechanism. The resulting bolt of energy produces an audible sound whose pitch – or musical note – is controlled using a familiar piano keyboard. Participants can play melodies made of pure energy.

Copper Urchin
Copper Urchin is a musical sculpture that is played by stroking its robust set of “sensory whiskers.” Here the participant is able to experience the sensation of creating musical sound while their hands are enveloped in a responsive and malleable medium. The whiskers are metal wires that when deflected cause a musical note to play. An amber light at the base of each sensor illuminates to indicate that it has been deflected to a sufficient degree and remains lit for the duration of the participant’s gesture.

The Energy Fluxion Band
The Energy Fluxion Band is a wearable device that displays the level of electromagnetic (EM) energy in the wearer’s immediate environment. It detects energetic radiations from an endless array of technological sources including cell phones, computers, radio transmitters and power lines. The project is meant to enhance the user’s awareness of the electromagnetic landscape that is produced by the generation, distribution and consumption of electrical energy. This terrain pervades our lives, but typically goes unnoticed.
