Louis Armstrong and his Hot Five. Armstrong’s wife, pianist Lil Hardin, is at far right, next to Armstrong.
The rise of recording and broadcasting technologies led to the spread of jazz from New Orleans to the urban centers of the North in the 1920s.
Panel 1 of The Migration Series by Jacob Lawrence (1917-2000), showing Southern blacks boarding trains for the North.
What’s more, the Great Migration — the movement of millions of African-Americans from the rural South (where 90% of black Americans lived prior to 1915) to the urban centers of the North, which lasted roughly from 1916-1970 — further spread the jazz aesthetic. Chicago became a center of black American life following World War I, and an important location for jazz recording.
In November 1925, trumpeter Louis Armstrong and his Hot Five made their first recordings for Okeh Records in Chicago. Armstrong’s ensemble was made up of New Orleans jazz musicians like himself; Armstrong had come to Chicago to play with Joe “King” Oliver’s Creole Jazz Band.
The 1925 recording session resulted in “My Heart” and “Yes! I’m in the Barrel.” You can hear the transformation of Armstrong’s style as a player from his work with King Oliver’s band, where essentially all the musicians “soloed” their improvised melodic lines at the same time. In the Okeh recordings, Armstrong emerges as a soloist who bases his ornate improvisation figures on the harmonic progression of the music.
