Black is the colour of the negative aesthetics of Adorno, and the true of our time. The aesthetics that thinks the radical art of our time, a black art, can only be a black aesthetics. The radical contemporary art is black art, and it is so because according to the aesthetic principle that constitutes the work of art as such - the spirit understood as mimesis - this one, the work of art, is writing of a blackened historical reality. What Adorno tries with black art is to return to art its right to exist after Auschwitz, in a discoloured world. But black art, as alive conscience of pain, as truth of the real, is already salvation, hope, utopia.
