His new book is The Limits of Power: The End of American Exceptionalism.

We speak with Stew (a.k.a. Mark Stewart), an indie rocker who's made his way to Broadway, as co-creator of the Tony Award-winning sensation, "Passing Strange." Hailed as one of the most original shows to hit the Great White Way in years, the loosely autobiographical show tells the story of a young black man who leaves his native Los Angeles for a life of sex, drugs and rock'n'roll in Europe. As Stew tells us, "Passing Strange" isn't a rock musical. But with smart lyrics, energetic tunes, an on-stage band and an electrifying ensemble of actors, "Passing Strange" is a musical that definitely rocks.
