I remember a television documentary that Channel 4 produced about Donald Judd after he died. I watched it in a video library in the basement of the monolithic concrete art block at Coventry University. Matthew Collings presented, looking very English, standing in the scorching Texan desert outside Judd’s compound. A talking head contem­porary of Judd’s, Richard Serra, explained how Don began his career as an art critic and used his monotone reviews of painting exhibitions to foreshadow his own elementary sculptures. I can’t actually recall, but I assume Collings delivered a comic parody of Judd’s writing. Something like: There is a painting. It is red. There is another painting. It is green. A yellow band extends from its bottom left corner half way along its bottom edge ... and so on.
