Ewerdt Hilgemann's 'Moments in a Stream' exhibition features seven monumental sculptures displayed along Park Avenue, NYC, from August 1 to November 7, 2014. Influenced by the German Zero Group, Hilgemann's work focuses on the interplay of geometry, nature, and contemporary life, utilizing materials such as stainless steel to reflect surroundings. The sculptures will be engineered for stability and safety against extreme weather, underscoring Hilgemann's extensive international exhibition career over the past 50 years.
