Paul Barbarin. He became leader of Duhé's band, playing at a number of Chicago clubs. In the summer of 1921 he took a group to the West Coast, playing engagements in San Francisco and Oakland, California. On the west coast, Oliver and his band engaged with the vaudeville tradition, performing in plantation outfits. Oliver and his band returned to Chicago in 1922, where they started playing in the Lincoln Gardens as King Oliver and his Creole Jazz Band. In addition to Oliver on cornet, the personnel included his protégé Louis Armstrong on second cornet, Baby Dodds on drums, Johnny Dodds on clarinet, Lil Hardin (later Armstrong's wife) on piano, Honoré Dutrey on trombone, and Bill Johnson on double bass. Recordings made by this group in 1923 for Gennett, Okeh, Paramount, and Columbia demonstrated the New Orleans style of collective improvisation, also known as Dixieland, and brought it to a larger audience. Because they were recording acousticly into a horn that was directly connected to the needle making the record master, Armstrong notably had to stand in the corner of the room, away from the horn, because his powerful playing bounced the needle off the master. In addition, white musicians would visit Lincoln Gardens in order to learn from Oliver and his band. Because Lincoln Gardens was in Chicago's black neighborhood and only admitted blacks, the white players listened outside near the front door. A prospective tour in the midwestern states ultimately broke up the band in 1924. In the mid-1920s Oliver enlarged his band to nine musicians, performing under the name King Oliver and his Dixie Syncopators, and began using more written arrangements with jazz solos. This band led by Oliver at the Plantation Café was in direct competition with Louis Armstrong's Sunset Stompers, who performed at the Sunset Café. In 1927 the band went to New York, but he disbanded it to do freelance jobs. In the later 1920s, he struggled with playing trumpet due to his gum disease, so he employed others to handle the solos, including his nephew Dave Nelson, Louis Metcalf, and Red Allen. He reunited the band in 1928, recording for Victor Talking Machine Company one year later. He continued with modest success until a downturn in the economy made it more difficult to find bookings. His periodontitis made playing the trumpet progressively difficult. He quit playing music in 1937. Work and influence As a
