The artist is Robert Irwin, whose work is already in the IMA's collection. Surely you've noticed this untitled piece.
But that was created back in 1969. To get some idea what we might be in for, here's a look at a more recent Irwin piece from the Museum of Contemporary Art San Diego.
The new 60-foot-tall piece, made of scrim and flourescent lights, created for the IMA, will climb the area in front of the gallery escalators. It will be unveiled October 11 as part of the IMA's 125th anniversary celebration.
