The Rhythmakers, sometimes known as The Rhythmakers or the Chicago Rhythm Kings in later re-issues, were a jazz recording group active in 1932. Organized by American music publisher and jazz impresario Irving Mills, the group was initially formed to feature and promote the singer Billy Banks. The ensemble was racially integrated, which was notable during a time when racial segregation laws in the United States prevented them from touring or performing publicly. Despite these restrictions, their recordings gained popularity and helped support the concept of racially integrated music groups.

The group recorded music in six sessions in New York City, featuring a lineup of talented musicians including trumpeter Red Allen, clarinet and saxophone player Pee Wee Russell, banjoist Eddie Condon, pianist Joe Sullivan, double bassist Al Morgan, and guitarist Jack Bland. Drummer Gene Krupa participated in the first session before being replaced by Zutty Singleton for the remaining sessions. Notable changes in personnel during the sessions included Fats Waller replacing Sullivan on piano, Pops Foster replacing Morgan on double bass, and Jimmy Lord taking over the clarinet parts from Russell. In the final session, Frank Froeba replaced Waller on piano, Chick Bullock succeeded Banks as the vocalist, and Tommy Dorsey was added as a trombonist.

The Rhythmakers' recordings are celebrated for their hot, driving sound and the brilliant chemistry between musicians like Pee Wee Russell and Henry 'Red' Allen. Although they never performed live due to segregation laws, their recorded tracks have become highly prized by musicians, collectors, and jazz enthusiasts. Billy Banks, known for his gender-bending vocals, had a parallel career as a female impersonator and eventually settled in Tokyo, Japan. The legacy of The Rhythmakers endures as a testament to the passionate spirit and improvisatory nature of jazz.
