"I am an American, Chicago born – Chicago, that somber city – and go at things as I have taught myself, free-style, and will make the record in my own way: first to knock, first admitted; sometimes an innocent knock, sometimes a not so innocent. But a man's character is his fate, says Heraclitus, and in the end there isn't any way to disguise the nature of the knocks by acoustical work on the door or gloving the knuckles."
