Oscar Wilde, another Londoner who used to prowl around the East End, said that while he'd used his talent for his works of art, "I have put my genius into my life." Tracey Emin can't make any such distinction - her work is her life. I suspect that's why, in this little corner of the 21st century, she is a genuine pop star. She's our accessible genius. The fact that she works to make a cult of herself, her personal dramas of life and love and the resulting mess, would be nothing strange if her medium was music or fiction. But never before, so blatantly, has anyone done it for the stuff millionaires buy to hang on the wall.
