For the last in our behind-the-scenes posts, we followed the process of installing one of the most technically complex works in the show: Witness 2000.

Hundreds of small speakers are suspended from the ceiling, each one playing a personal account of a sighting of a UFO, creating a murmuring soundscape. Susan has said about this work:

“Listening to these people whispering in your ears is like being a priest in a confessional. The whole piece is built upon the shape of the cross and the circle. There are four pathways where you can enter the inner circle of the installation… The religious symbolism of the cross in the circle is crucial because the stories are examples of contemporary visionary experience. Only today people see UFOs where once they saw angels.”

We got an insight into how the work is technically put together from Design Engineer Adrian Fogarty. Adrian works on the technical design and installation of many large-scale installation works and for Witness he was closely involved in the technical build. In this video, he gives us an insight into parts of the process, from engineering the audio to realising the symbolic structure in the physical space.

"like being a priest in a Confessional" what an insulting thing to say.


I was quite disappointed when i came to see this work on the day the exhibition opened as there was only one 'soundtrack' playing from the same speaker and i understood there was supposed to be 10 tracks circulating around the piece.

I absolutely love this work and from watching this video i can see the difficulty with the technical side but it was still a shame to not have seen it in its 'full glory'


It starts with one voice and then the others join in after a little while.

The video reveals just how much efffort it takes to create (or recreate) a work like Witness, which I found (posted one of the most impressive in the Hiller show.

One of the best sound works I've ever seen/heard!
