After the First World War there was a boom in jazz for a decade that has come to be known as 'The Jazz Age'. This was the era of the earliest dance music, with the Charleston  and something known as the 'Black Bottom' being particularly popular. Musicians from the south moved etc Chicago looking for work, and the Chicago style was born. New Orleans musicians like the New Orleans Rhythm Kings, King Oliver's Creole Jazz Band and Jelly Roll Morton all made their way to the windy city. Leading bands of the time include Fletcher Henderson, Paul Whiteman and Duke Ellington.
