The Ceeb has a piece about American artist Barbara Kruger, who has brought her "pop-art propaganda" to Toronto's AGO. The article includes several examples of Kruger's "edgy" installations.
How "edgy" is she?
So "edgy" that she makes fun of--wait for it--George W. Bush.
So "edgy" that she mocks materialistic consumers, who "shop, therefore I am."
In other words, about as "edgy" as a dull knife.
In our time, of course, the artists who are truly bold and transgressive and "out there" are not the ones hitting the obvious targets. They are the ones drawing 'toons of Muhammad.
