"In 1956, unlike art informel, Mack developed his first Dynamic Structures - paintings in which in a singular manner a painting of light is contrasted with traditional colourism and structure replaces composition. He created new surfaces which appear to vibrate and which give the impression of three-dimensional reliefs by means of a use of colour which was increasingly reduced to black and white and grid-like structures. Despite the radical restriction of means no two paintings are alike. In its focus on the early works of the ZERO period, this volume provides an indispensable key to an understanding of Mack's work as a whole"--Publisher's website.
