The work of the conceptual artist Loris Gréaud includes installations, films, and architecture, and his long-term project taking place around the world, The Unplayed Notes is no exception. Viewers encounter an experimental field of diverse media, all of which attempt to give form to temperature, light waves, or time. Gréaud is interested in the stages of artistic production. The process of searching per se becomes visible in his installations. This book invites readers to travel through a host of fantastical stories, from the (sur)natural history museum cleverly vandalized to the reactivation, as poetic as it is disturbing, of an old glass factory to the burial ad vitam of sculptures in a subterranean park in the heart of the desert-in accordance with the ideas of Karlheinz Stockhausen, which gave the book and this series of projects their name: the actual meaning of a work lies in its unplayed, unheard notes.Yet, the monolith features more than 300 hundred art works spread across 500 pages and traces eight years of aesthetic experiments and adventures from Paris, New York, Dallas, Venice to Puerto Escondido, Mexico. It includes one complementary essay by the artist's long-time collaborator, outstanding theorist, and curator Nicolas Bourriaud.LORIS GRÉAUD (*1979, Eaubonne) is a French conceptual artist. His works are part of prominent collections, and have been presented in museum and gallery exhibitions around the globe.
