It was a music very characteristic of its time, forever preserving the sound of Jazz Age Chicago on shellac records. But the Jazz Age could not live forever and Chicago’s role in the development of jazz could not always keep stranglehold of its power on the music. Jazz, especially, is a music that always moves, always evolves. And when the music moves on, it takes on a new form, it transforms into something new and something more timely for the new era.
And while it is a simple fact that change is inevitable and that pop culture will always shapeshift to better fit the times, this common fact of nature is not the lone force that brought the demise of Chicago-style jazz. Rather, alongside this natural change there were specific factors, societal and musical, that contributed to the fall of the Chicago-style and the rise of swing.
