Big city impressions, triggered by stays in Paris, London and New York, environmental sounds and jazz - his father is a jazz musician - play a central role in Sonderborg's work. Since the early fifties, Sonderborg has come into contact with American action painting. With spontaneous application of paint, he achieves the depiction of a structural fabric that makes form visible in a state of becoming. Thus Sonderborg's work is far closer to American gestural painting than to European Informel.
Next to Gerhard Hoehme, K. O. Götz, Bernhard Schulze, Hann Trier and Peter Brüning, Karl Rudolf Hoffmann from Sonderborg (Denmark) is one of the most important and powerful representatives of German informal painting. Painting and drawing process leave visible traces. His pictorial inventions transform matter through the speed and rapid force of the order into energy, which remains palpable even before the lithographs and etchings.
