Susan Hiller exhibition

Went to the Susan Hiller exhibition at Tate Britain with a few people from uni. I was most interested in an installation titled 'Witness'. The piece was visually stunning, a calming feel but then unsettling. The sound from the suspended speakers of different peoples experiences of seeing UFO's (various languages spoken), all the voices talking at the same time gave a confusing and eery feel. I wanted to listen in to each account but it became distracting and confusing, i like the feeling of this mix of responses to the piece.
