Chicago and New York as the Incubators for American Jazz

    The 1920's was a huge decade for the phenomena known as "Jazz".  
Due to the closing of the seaport in New Orleans, musicians were

The clubs there were known to hire the "who's who" of blues musicians.
The last major style of jazz to emerge from Chicago during the '20's
