In Chicago there is no past waiting to jump on Henry. Music is everywhere, in the streets, in nightclubs, on phonograph records: furious, wild, happy music played by a man with a trumpet and bleeding lips called Louis Armstrong.

Armstrong needs a man, a white man, and the man he chooses is Henry Smart.
