One of the things really good conceptual art can do is force a debate about what the hell constitutes art in the first place. This visit to the Sun Tunnels will do one of two things: Fill you with a deep burning need to drive four hours outside of Salt Lake City to experience a set of concrete tunnel sections lined up with the winter and summer solstice. Or its excessive mellowness and ersatz beat sensibilities will send you running for fresh air and a Big Mac. Both reactions would be completely valid. Which makes this little item such an interesting auditory Rorshach test.
