Using examples of works by Nam June Paik (1932-2006), the hugely influential Korean American artist who is considered the progenitor of video art, he author explores the relation between the artworks' concept and material, theories of musical performance and performativity, and the Bergsonian concept of duration.
"The author does not only offer an analysis of the installations in the traditional context of conservation of works of art, that is to say in the conditions of observation, measurement and analysis. Rather, it seeks to understand their conception in a regime of cultural, scientific and dynamic relationships. The book takes its originality from the museographic approach, which is broken down into three parts: the first, "Concept and Materiality", where artistic and performative media are mentioned; the second, “Time and Changeability”, which deals with questions of time and conservation; and the third, "Archive and Identity", where the concepts of the material and immaterial archive are advanced, with archival and museographic implications."
