Earlier this year I was invited to Norwich to talk about the palimpsest, the subject of my early work but a topic to which I had not returned in recent years. At the symposium I met a talented young designer and filmmaker, Michael James Lewis, who challenged me to consider how the metaphor of the palimpsest might help us think about the contemporary digital age, in particular cloud computing and remote data storage. He did indeed get me thinking, so during the summer he came to visit me in Cambridge and we recorded a long interview on the topic as part of his project, ‘The Cloud is More than Air and Water’. Michael has now turned the interview into a sound piece intercut with his own work and backed by new music composed by his collaborator, Matt Parker, out of sounds recorded at a data storage site. Part I of the recording is now available here, with Part II following shortly.
