As of tomorrow kerry tribe will be showing her video works 'Dead Star Light' at the Arnolfini. I saw it at the Whitney in NY in August and was blown away. It is made up of three peices. The one I saw was a video piece about a man who suffers from memory loss. The installation is made up of the same video being show twice alongside each other with a 20 second delay between them, causing the audience to be left with feelings of memory confusion.
Definitely worth checking out! and it's free.
