I was in Johannesburg in 1993, before the rise of the anti-apartheid government, when the streets throbbed with uncertainty about the future. The political leadership was trying to decide if the fall of apartheid would be peaceful or bloody. The ambiguity hanging in the air made it hard to get a bead on the general direction of things. But you could find clues. You just had to search for them among the people of that huge industrial city, in their voices, their writings and especially, in their art.
