Louis Armstrong Records the Hot Seven Sessions

In 1927, Louis Armstrong recorded his Hot Seven sessions for Okeh Records, extending the small-group format of the Hot Five with additional horns. The recordings—including 'Potato Head Blues' and 'Struttin' With Some Barbecue'—deepened the revolution of the earlier sessions and confirmed Armstrong as the defining voice of jazz. His cornet and later trumpet playing set standards of melodic invention and technical mastery that transformed American music.
