All wrapped up in JAZZZZZ!

After learning a bit more about the Jazz age and how African American people were discriminated against there are a few questions that stir in my mind. For starters Duke Ellington is probably known as one of the best Jazz musicians of all time, did he ever recieve full compensation for his work? Or did race still come between his music and chance for earning compensation? Also was there a group of people who boycotted jazz music due to so many African American Musicians?
