What do we all use, but never visit? The sound artist Matt Parker takes us inside the bizarre world of remote Data Centres, where our wireless world is powered by rows and rows of computers running all day, everyday. But what is the true cost of these centres to our planet? What do they sound like? And why does one have an empty white room with an executive leather armchair and a faceless portrait hanging on the wall? James Ward introduces another curious talk about a subject that may seem boring, but is actually very interesting.... maybe.
