As far as this gallery of the University of Chicago’s campus is concerned, the avantest of the avant-garde is the only one that matters. As for the name, well, the university wants to broaden the definition of renaissance. (Think less Michelangelo, more the Next Michelangelo, in other words.) The white walls and high ceiling create a hyper-resonant environment. Many European avant-garde stars get their only Chicago exposure here, and the shows are free.
