Kenny G is not real jazz. I don't even think Wynton Marsalis is real jazz. I don't think Harry Connick Jr. is real jazz. If there is such a thing as real jazz, The Lounge Lizards is real jazz, Henry Threadgill is real jazz, Bill Frisell is real jazz, you know?
In the same way that so many people read 'Harry Potter' and went to see 'Harry Potter,' just because a movie is about a kid, doesn't mean it's for kids, and just because a movie is about a girl, doesn't mean it's for girls.
