Bruce Nauman – Raw Materials : Tate Modern 2005
extract from the page above
The unusual formula of his Theatre of Death consisted in creating artistic illustration for mechanisms of memory. Sequences of unreal pictures, snatches of memories, obtrusively returning scenes, and absurd situations: everybody knows this from his own experience. And all of us are confused in a similar way: series of painful resentments, daring longings, remembered fragments of sentences, comical scraps of the past. We are physical, and it appears that our memory and imagination are also physical. We do not exist without form; we think and even feel with images. And Kantor could show it on the stage. He created an unusually suggestive space in which the living and the dead have been mixed, where the shyest desires and most cruel experiences, i.e. war, love and crime, fear, passion and hatred have been revealed. On faded photographs of his family album, the personal biography intertwined with history, where national myths and private obsessions returned with tiresome echoes, like in the distorting mirror.
