With all eyes on Doug Aitken’s “SONG 1” video installation, which closes this weekend after an extended run, it is a good moment to consider the Hirshhorn Museum and Sculpture Garden on the National Mall as architect Gordon Bunshaft intended, and through the lens of photographer Ezra Stoller, who captured the images in this slide show shortly after the institution's opening in 1974. Aitken’s installation reimagines the round form of the Hirshhorn as an inverted 360-degree Cinerama screen; projectors cast video onto the building’s exterior, while a soundtrack of several variations on The Flamingos’ hit “I Only Have Eyes For You” repeats on loop. Stoller’s images show the Hirshhorn speaking for itself, and with a working central fountain.
