Peter Brüning is considered a main representative of the Informel in Germany. Marie-Luise Otten has called him a "lyricist of German Informel." While Brüning's painting was initially characterized by dark colors, his style lightened up in the early 1960s. Brüning became more gestural, generous and dynamic. At the beginning of the 1960s, he looked for new ways to translate the reality of our time into landscape paintings in a symbolic way. Our landscapes changed by technical progress with their traffic routes and power pylons motivated Brüning to cybernetic landscape representations.
As spontaneous and energetic the images seem, so considered is his composition. Round, curved shapes and concrete, graphic elements complement each other to the charming overall picture. Nature impressions and contemporary cartographic formulas and pictograms are not a contradiction, but unite to a common harmony, to sign-like abbreviations of our time.
