The speaker does not refer to a specific dream.

Following the war, black music, especially the blues and jazz, became increasingly popular with both black and white audiences. Europe continued his career as a successful bandleader until his untimely death in 1919. Ma Rainey and other jazz artists and blues singers began to sign recording contracts, initially with African American record companies like Black Swan Records, but very quickly with Paramount, Columbia, and other mainstream recording outlets. In Harlem, one club opened after another, each featuring jazz orchestras or blues singers. Noble Sissle, of course, was one of the team behind the production of Shuffle Along , which opened Broadway up to Chocolate Dandies and a series of other black musical comedies, featuring these new musical styles.
