John Yau: “It is not that I was dissatisfied more than usual with what I had written. Writers are always vexed by what they have written. In this case, something else about the works wouldn’t leave me alone. The impetus came from pieces that I did and didn’t write about. I decided to go back to the exhibition and look again. I wanted to figure out what I had not gotten to the first time, and which could not wait.”
