Alibis: Sigmar Polke. 1963-2010.
Blockbuster.
Experience- short lived hilarity becomes disturbing really fast (a show not for the faint-hearted).With work inspired by social media and the 2nd World War in Germany. There are many references to history, repetition, remembrance, monumental and the brutality of the human condition.
