Much has been written about Heinz Mack, but this book truly stands out. Recounting his life through the pen of Robert Fleck, the artist himself gives us deep insights into the motivations and goals of his artistic work - almost as if we were sitting in conversation with this fascinating and renowned figure. A world-class artist is at once simple and very complex. On the one hand, a human being, like all of us, on the other, permeated by a web of motifs and ideas that one can scarcely guess at. Based on numerous conversations since 2020, the present volume explores this charged duality in Heinz Mack. We follow the artist closely through his eventful life, from the years of the Second World War to the present day. Like a second voice, original quotes placed in the margin accompany the narrative and lend this unusual biography its unique charm.
