The Witness Engines connect directly to live data feeds and process the incoming datastream into sound.
Developed by award winning composer and sound artist, Michael Begg, the Witness Engines consume environmental and climate data which is then transformed into music.
This is no ordinary music – it lives and evolves, dynamically, in real time for so long as the engine remains on and active.
The Witness Engines offer new perspectives, and new modes of engagement to our sense of solastalgia our anxiety concerning our environmental crises.
For the scientific research community, the Witness Engines provide unprecedented potential for outreach and engagement.
