In connection with the exhibition 'Tetrachromat' by Tauba Auerbach, Bergen Kunsthall and Sternberg Press are publishing a new book that presents Auerbach's ongoing series of "Fold" paintings for the first time in book form. In these paintings Auerbach twists and folds the canvas before applying the paint. In its stretched form the flat canvas retains a trompe l'oeil rendering of its previous three-dimensional state. Transferred to the medium of the book, the paintings are presented here in a new and unexpected way alongside mathematical diagrams and three texts. Auerbach works with a number of printed media, and the book enjoys a quite central position in her oeuvre: from highly sophisticated book sculptures that are somewhere between physical objects and non-narrative books, to a series of individually made artist books - a pop-up book where six detailed paper sculptures emerge from the book's pages.
