Ernesto Neto (b. Rio de Janeiro 1964) is one of the most important proponents of the Neo-Concrete movement, an art trend that started in Brazil in the 1950's. The exhibition "Ernesto's Toungue" was a retrospective comprising a selection of sculptures and installations created by artist Ernesto Neto in the last 24 years. The exhibition, described as a playground with sensorial and interactive possibilities includes drawings, sculptures, photographs and his small and monumental abstract installations that invited the visitor to smell, feel, touch, listen and use them and where the main elements and materials used in his works are the elasticity of the fabrics, the force of gravity, spices and polythene foam. The present book published on the occasion of the exhibition "gathers and organizes works and images in order to begin to envision a wider panoramic view of Ernesto's oeuvre. For this publication we selected in close dialogue with the artist the most significant exhibitions and projects since 1968, thus encompassing 25 years of production (...) we documented all of Ernesto Neto's individual exhibition catalogues, reproducing them in the book. The codifying and cataloguing drives led us to organize the book in a strictly chronological manner, privileging exhibitions over individual works"--P. [9].
