Cornelia Parker has been a favorite of mine since I saw her lecture at the SF Yerba Buena years ago. She was showing her pieces "Mass (Colder, Darker Matter)" and "Anti-mass" (above). "Mass" is salvaged materials from a church from the American South that was struck by lightning and "Anti-mass" was salvage from a church burnt by arson. She suspended both huge installations in the same room in diagonal corners from each other. They were powerful pieces to witness and intense displays of the fragility of the human experience. I remember spending a lot of time in that space.
"I resurrect things that have been killed off... My work is all about the potential of materials - even when it looks like they've lost all possibilities." Cornelia Parker
