Jazz Ltd.

Jazz Ltd. was a Dixieland jazz band, nightclub and a record label in Chicago.

For 31 years Jazz, Ltd renewed public interest in Dixieland jazz music—when swing music, then Bebop, then rock and roll were the dominant styles. It was the first jazz club owned by a musician in Chicago. It provided a steady job to many jazz musicians at a time when they needed one. The owners Bill and Ruth Reinhardt estimated that over 700 musicians played at Jazz Ltd.

By hiring the best jazz musicians in the country, forbidding singing and dancing (which incurred a 20% war excise tax that put many jazz bands out of business), refusing business with the mob and playing only Dixieland jazz music, Jazz, Ltd became one of the longest-running jazz clubs in the country.
