Once the place where Judy Garland sang “Somewhere Over the Rainbow,” Sony Pictures Entertainment will soon exist under one in the form of an expansive, steel arc.

“Rainbow,” a piece of public art by American multimedia artist Tony Tasset, has been in development since last June and will span from the Culver City studio’s Thalberg Building to the Madison Gate. The polychrome installation is 94 feet tall by 188 feet across and planned to be unveiled at the studio in mid-October with an accompanying media reception. Construction of “Rainbow” is currently under way offsite.
