I was previously unfamiliar with the architecture of the Aspen Art Museum, having visited only before the current building, designed by Shigeru Ban, opened in 2014. My ignorance turned out to be helpful, enabling me to be properly confused by Jacqueline Humphries’s painting installation TSLA (2025). I first saw it, the night before the artist’s survey show opened, through the plate glass wall at the museum’s entrance: five large canvases (8 by 7 1/2 feet), her usual near-squares) hung closely but not quite touching, and not on a wall but on a structure of bare metal framing studs.
