Chicago

New Orleans music migrates to Chicago and the Jazz Age (1920-29) blossoms. Over 40 well known jazz players move to Chicago from New Orleans. 
1916 Johnny Stein plays at 'Schiller's Cafe' with La Rocca's lead horn, the band transforms into the ODJB which relocate to New York in 1917 and becomes a sensation at 'Reisenweber's'.
1923 King Joe Oliver and Louis. The Creole Jazz Band at Dreamland.  
Rocking rhythm. Punchy lead. Harmonies behind the lead. 
Art Hickman, Paul Whiteman and early Fletcher Henderson pushed Oliver into The Dixie Syncopators 'big band' in 1926
1923 NORK take the ODJB's music further, a fresh repertoire, swinging ensembles and a more advanced rhythm section. Jelly Roll Morton sits in with the New Orleans Rhythm Kings and helps to break down the colour barrier. 
The Austin High School Gang - the 'white' maestros - the Condon mob. Benny and Ben Pollack.
Bix, Tram and Goldkette. It's impossible to play the same way twice, I don't feel the same way twice. What I like about jazz is I never know what is going to happen next, do you?

Spencer Williams (1889-1965) - raised in Storyville by Lulu White of Mahogany Hall fame. He moved to Chicago in 1907. His first hit 'I Ain't got Nobody' in 1914. Then in 1916 his first Blues 'Paradise Blues', then in 1917 a hot dance number, 'Shim Mee Sha Wabble', then 'Tishomingo Blues'. What a sequence!
In 1919 his starts his collaboration with Clarence Williams. 'I Ain't Gonna Give Nobody None of this Jelly Roll', 'Yama Yama Blues', 'Royal Garden Blues' (the first 'riff' song).
Both moved to New York in 1921. 'Everybody Loves My Baby', 'I Found a New Baby'. And his big break 'La Revue Negre' with 19 year old dancer Josephine Baker in France. In the chorus in 'Shuffle Along' and 'Chocolate Dandies'. 'Wiggling and jiggling in a fashion to outdo a congress of eels'! France was ready for American music and sex.
Spencer Williams became a Parisian and in Sudbury on Thames, a Londoner. But never forget 'Basin Street Blues' with Jack Teagarden, 'When Lights are Low' with Benny Carter and 'It's the Bluest Kind of Blues' with Django.

The Jazz Age moves to New York - speakeasys become numerous and offer numerous opportunities to jazz musicians. By 1927, Coleman Hawkins loses his 'slap tongue' style of playing tenor sax. He learns from Louis and starts improving by using the notes of chords in the song instead of just basing the improvisation on melodies in the song. This new style was less coherent, but a big step leading to more modern forms of jazz. Towards the end of the 1920's Classic Blues declines as Swing gains in popularity. Also dying was the New Orleans style music. Armstrong drops the New Orleans style and with it many of his players from New Orleans. At the very end of the 1920's the Great Depression hits.
