It’s not a post-mortem if the body is still breathing. So what Pitchfork and Art Institute executives delivered late Friday, as the final sets wound down, might be considered more of a mid-mortem, or maybe a pre-post-mortem. In any event both sides pronounced themselves almost wholly pleased with how things had gone on night one. For two and three, they need to tell people having the special dinner at Terzo Piano to just go straight there off of Monroe Street, in order to avoid being escorted through the separately ticketed venue Griffin Court to reach the restaurant, said Pitchfork’s Adam Krefman. And both he and the Art Institute’s Jackie Terrassa said they were surprised at how much the Grand Staircase and the museum cafeteria served as hangout spaces. (Perhaps this was not so surprising, though, as each held a bar that was accessible to all ticket holders.) They liked how the recorded musical soundscapes were working in various galleries, the drawing exercise that was popular in the Native American gallery and, as Krefman put it, “the choose-your-own-adventure element to it.” Meanwhile, reported Terrassa, she had heard no reports of incidents involving destructive artwork-patron interaction. There was a potential glitch as the first night ended at close to midnight: Museum guards were telling patrons the main, Michigan Avenue museum entrance had closed, meaning those who had checked coats there would have to walk across the museum to get them, then all the way back across to get out. But minutes later, wiser heads appeared to have prevailed and patrons were spotted exiting via the Michigan doors.
