"It was much more communal. It was the late '60s, there was a very different attitude toward artists and work. There was very little money involved. I mean, this is before contemporary art was sold for very large sums. I think we were amazed that what we were making would even be bought. Our type of work was somehow counterculture. We chose materials that were not "high art"; we weren't working in bronze, or paint, even. We were using materials that weren't previously considered art materials. They were deliberately chosen to psychologically evoke certain kinds of feelings. I use psychologically loaded materials."
