| The Rise and Fall of Black Swan Records (3953 words) |
| Fletcher Henderson was the pianist of record on all Black Swan releases from the start until the Fall of 1921. |
| It was in the Summer of 1921 that Ethel Waters came to the rescue of Black Swan Records. |
| It was ironic that at the time of its earliest success Black Swan had the opportunity to record and sign Bessie Smith, who would later become legendary as the "Queen of the Blues." Harry Pace upon hearing her sing one night decided that she was too "nitty gritty" for his taste. |
