A book for Javi Cruz´s solo show in CA2M, Museum of Contemporary Art of Madrid. Trémula is a show about a dead nature, one and multiple bodies, processes of transformation, construction and reconstruction. The book embodies this through its process of manufacturing and printing. From the sheet to the pages, from the issue to the stack of books. The artist ́s system of writing connects the contiguous pages that would later be split to form the book, in a semi secret gesture only witnessed by the printer operators.
