Jazz music is world music. It grew up in America from seeds that came here from Africa and many other nations. From its birth in the Deep South, jazz spread north to Chicago, east to New York and beyond, to the West Coast, then Europe and the Orient. This blog is dedicated to the music and those who play it and who love it. The blog also salutes KCSM Jazz Radio, whose talented announcers send great jazz streaming over the Web throughout the world from the San Francisco Bay Area.
