In 'seeking' we may travel far. At least we believe we have travelled. Sometimes the thing we seek is with us all along, in all its beauty, intrigue or ugliness. We just don't know it. The great explorers travelled to the 'unknown', looking for treasures and new lands. Some of the greatest are rumoured to have described fictional adventures, travelling only in their imagination. Maybe what they sought was of a different nature to what they thought. Exploratio Invisibilis carries the listener on their own 30-minute voyage through a three-dimensional energy filled electronic landscape of implication, sound, and silence. To the south.

Confronted storms, traversed rivers, plunging into the ocean, submerged.

shards, bubbles
heavy breath.
Breaking through.
The whole pack was in motion, as if impelled by some mysterious force.
Pressing onward.

The haze suddenly dispersed.

Revealed. Treasured.



Exploratio Invisibilis uses encoded 3-D sound, decoded over 12 loudspeakers arranged spherically above, below and around the listener.

This spatialisation is achieved using the second-order ambisonics format. Unlike conventional surround-sound systems, ambisonics provides a means to synthesise a continuous sound field as experienced in reality.

Exploratio Invisibilis was commissioned by the Ultima Festival 2003, and produced by NoTAM & Barrett.
