The exhibition “Fred Sandback – Negativa” at the Metropol Kunstraum focuses on a specific aspect of the multifaceted work of artist Fred Sandback. Known for his minimalist spatial drawings made of colored acrylic threads, Sandback explored the perception of space, line, and volume in a unique way. In the reliefs and prints on display, Sandback approaches the subtle relationships between surface, space, and perception from the opposite direction using entirely different means.
