Input: Question: When was the country and western label based in Chicago formed? Passage:Black Jazz Records was a jazz record company and label founded in Oakland, California by pianist Gene Russell (December 2, 1932 - May 3, 1981) and percussionist Dick Schory. The label was created to promote the talents of young African American jazz musicians and singers, and released twenty albums between 1971 and 1975. Some of the more notable artists to record for Black Jazz Records were Cleveland Eaton, former bassist for Count Basie and Ramsey Lewis, and organist/pianist Doug Carn, whose four albums were the most successful of any Black Jazz artist. Carn's wife at the time, Jean Carn, sang on his albums; she changed her name to Jean Carne and went on to have a successful solo career as an R & B singer. Singer Kellee Patterson gained notoriety as the first black Miss Indiana in 1971, before recording her debut album, Maiden Voyage, with Black Jazz Records in 1973. The label was distributed and financed by Ovation Records, a country and western label based in Chicago, which was also founded by Schory. Black Jazz Records was considered at the time to be the first jazz label started by an African American since brothers John and Reb Spikes started Sunshine Records in 1921.
