Is a new interactive installation at the ICA art or massage therapy? By Judith Palmer

GASTARBYTER, a new interactive installation at the ICA, may well be the best-value massage in town. It is the kind of thing you might expect to find in a dodgy Japanese executive hotel, but instead you can try out this particular sensory experience by booking yourself a 10-minute solo session in a darkened theatre.

This strange contraption has been developed by artists Bruce Gilchrist and Jo Joelson with Dugal McKinnon, an electroacoustic composer, to create an auditory, visual and supremely tactile encounter.

Making my way through a gap in the black rubber awnings, I emerged in a spacious square chamber, with a large two-way mirror hung on each of its walls. Squatting like a mosquito in the centre of the floor is a steel chair, which judders on its springy joints as I climb aboard.

With my head snugly cushioned by a rubber headrest, arms and legs outstretched, a host of bouncy pads around the seat and back. Once in position, I am quite comfortable, although the initial mounting manoeuvre requires a level of mobility which dictates against wearing Rod Stewart-tight trousers or a thigh-high mini.

So, there you are, immobile in this contraption, remembering past trips to the dentist or gynaecologist, when the music begins and your chair starts spontaneously quivering. And, well - mmm, it is really rather pleasurable.

Four neon tubes in front of you, more on the edge of your peripheral vision, spring into fizzling life, triggered by the varying pitches of the enveloping soundscape. Flowing red lines zip on and off, occasionally turning blue, as the neon hits a pocket of mercury.

A low revving hum sends a brief tingle up one leg, a couple of deep bongs and your buttocks get a delicate pummelling, then, joy, a sustained vibro-massage of the lower back.

It is like sitting watching the dying glow of a four-bar electric fire with each foot on the pedal of an electric sewing machine, reverberations travelling up and down the body.

Lights and chair-sensors react in harmony with the shifting electronic noise, jiggle to a few short percussive tones, then surf down a long, mesmerising gong until you are literally inhabiting the interior landscape of the sound.

Suddenly, there is a change of tempo: the neon dances frantically and your whole body buzzes with vibration. This is probably how it feels to be a bluebottle frazzling on a kebab-shop insect-o-cutor.

In our increasingly visual culture, we are usually cut off from our proprioceptive powers. Unless you make a habit of standing on overhead motorway bridges or clamping yourself to the speakers at a Metallica concert, you very rarely get the chance to actually feel sound.

Gastarbyter, I assure you, is an infinitely more subtle alternative. As the Beach Boys had it. Good, good, good, good vibrations.
