Non-conformist and daring, German artist Heinz Mack recently turned his attention back to the canvas, after a break of more than twenty years. In the new works reproduced in this volume, Mack translates light, movement, and immateriality into the glowing worlds of the colors of the chromatic spectrum. Through the exploration of the juxtaposition of colors and visible brushstrokes in the genre of the monumental panel picture, he opens up a view of the infinite, the boundless, and the immaterial. Along with stunning full-color reproductions of Mack’s work, the book includes conversations and letters in which he explains his ideas and sources of inspiration.
