Here’s a perfect example of how Nashville’s art institutions elevate local art: Last year Frist’s contemporary gallery exhibited U-Ram Choe’s excellent installation of H.R. Giger-esque animatronic sculptures New Urban Species. Now, local artist Ryan Hogan is making work that is directly inspired by his experience with the exhibit. At first glance, Expanse, opening today at Seed Space — the gallery-within-a-studio in the 100-year old May Hosiery Mill building on Chestnut Street — looks nothing like Choe’s work, which is like a combination of the monster in Alien and a postmodern robotic garden made from scrapped jet engines. Hogan’s work, on the other hand, is organic, like light hidden in amber, or Serrano’s “Piss Christ” — but the work is lit from within and pulsates in irregular but organic patterns, much like the movement of Choe’s sculptures. It is heartening to see local artists find inspiration in strong contemporary art exhibits like Choe’s as they continue the dialogue about the line between organic and inorganic, art and science.
