The Wall Street Journal’s art correspondent, Kelly Crow, spoke to Gregory Miller about his collection which includes works by Adrian Piper, Glenn Ligon, Mark Bradford, Ghada Amer and Catherine Opie. Here’s how he tries to explain his passion for one of his acquisitions:

Last year we bought a Fred Sandback sculpture called ‘Eight-Part Vertical Construction.’ What we bought was eight long strings of yarn in four different colors like white, black, red and gray. The strings go straight up from the floor to the ceiling.

They’re paired, but the space between some of the strings is narrow and the space between others is farther apart. When you stand back, the strings look like they’re defining actual spaces as though you’re looking through invisible walls. It’s the same living room, but now I start to think about walking through or around it in a new way.

“And the nice thing about that yarn? Whenever it falls down, you can hire a person who’s authorized by the Sandback estate to come string up another piece of yarn.
