My favorites are Stevie Wonder and Marvin Gaye, but those are a little off in terms of getting Detroit right on the head. But of course, you know, "Dancing In The Streets." You can't forget the Motor City. And we can't forget the Motor City.

I look for two things when I am about to launch into a book. First, there has to be a dramatic arc to the story itself that will carry me, and the reader, from beginning to end. Second, the story has to weave through larger themes that can illuminate the world of the subject.

Well, here you had a city that was selling more cars than ever before, that had this wondrous music being created, that was so vital to the labor and civil rights of this country, and yet it was dying and didn't see it, except for some sociologist at Wayne State University who predicted that Detroit was losing population by a half-million by the end of that '60s decade, and that that trend would continue taking away its tax base.

Detroit was an exaggeration of what was going on across the country. You could see the divisions, even within the Civil Rights Movement of that period. At the same time that Martin Luther King was talking about his dream, Malcolm X gave his most famous address in Detroit during that same period, "The Message To The Grass Roots," dismissing the notion of integration.

I want my books to last, to stand the test of time, and to do that I focus on the forces that shape the subject - the cultural and sociological geography - to capture them in a way that will explain them no matter what they are doing.

You also had in Detroit that summer, an early variation of Ferguson. A black prostitute was shot in the back by police. And all of the efforts that a very progressive police chief and mayor of that period had put into trying to restore race relations started to fall apart again, and you could see that unraveling for several years until the riots or rebellion of 1967.
