Agate author Eric Felten in his latest WSJ column, talking about how many of contemporary art's go-to moves just don't cut it anymore. He makes specific mention of Marcel Duchamp, whose importance to the conceptual art of the past 50 years cannot be underestimated. Lots of good perspective here on the way Pound's classic dictum to "make it new" is being failed by too many artists and writers at work today.
