If you are passing through the Walker Art Center anytime soon, set aside a few minutes to see “Slant/Light/Volume.” There’s just one piece in the show, an untitled work by Robert Irwin.

It’s quite simple: a huge piece of fabric stretched across an entire gallery at an angle, lit from behind. Seen in person, it is stunning, a glowing plane hanging among the faint echoes bouncing through the Walker’s chambered galleries.

The piece was designed for the opening of what was then the Walker’s new building in 1971. It hasn’t been displayed for 20 years, and it’s definately worth experiencing now.
