Arboreal Lightning is a vast site-specific interactive lighting installation weaving through the filigree architecture of the Camden Roundhouse.
It transforms sound and gesture into an immersive luminous experience, its tree-like fibres shimmering in response to music and movement Bundled LED strips burst from the stage and soar above the performers, their branches twining along the Roundhouse structure and into the heavens. The occasional strand stoops to greet and listen to its visitor, with 6 microphones distributed throughout the space, feeding the tree with the nectar of visitor interaction.
The project was commissioned from atmos by Imogen Heap as the centrepiece for the Camden Roundhouse's Reverb 2014 Festival - a smorgasbord of contemporary composers, with an emphasis on technological innovation. It was conceived and designed by atmos, programmed by Adam Stark, and built by a small army of brilliant volunteers.
The project mirrors the Roundhouse's clock-like plan of 24 columns by bundling 24 strands of LED light into a giant heavy-rooted trunk that grows from the stage to arc over the colonnade and arches above.
The strands soar upwards and weave through columns and rafters to follow the building's dramatic structure, seeking hidden recesses and unexplored corners, before exploding outwards above both the performers and audience.
Some branches yearn upwards, towards the light of the lantern; a few strands bow down to reach and mingle with the audience, who can then trigger their own luminous ripples and join in the spatial symphony. This light canopy of visual music creates a unifying lattice that embraces the people beneath it within a giant, pulsating, Gaian network - umbilical cords connecting people to building, sound to light.
1,500 metres of LED string have been meticulously tamed to shadow the contours of the building's giant skeleton - yet each of the 4,800 pixel nodes glimmer individually in response to life. They coalesce to form a sinuous elastic mesh of sculptural video; a fluid, spatial cinema, worming through the building.
Arboreal Lightning unleashes the hidden power of a place - and people. It explores inaccessible spaces and ineffable sensations - the physical manifestation of music, and the convergence of sensations. In an age of emancipated connectivity and collaboration, it seeks to reinvent and re-imagine the relationship between performer and audience, sound and light.
