To some extent, the market already penalizes avant-garde art created for its own sake. I'm just not sure how critics should respond. If the critics bubble effusively about how great
Blue and
4'33 are, what exactly are we supposed to do with that criticism, as either artists or patrons?
To me, works like these are symptoms of art forms that are well on their way to exhausting their own possibilities. What next? Green? 4'34?
