Historians can't seem to nail down an exact date for the birth of African-American composer Scott Joplin, but they think he was born between 149-150 years ago, probably in November 1868. This Fishko Files invites his biographer Edward Berlin to consider Joplin's life, and offers a taste of his now-celebrated work, from "Maple Leaf Rag" to "Treemonisha." (Produced in 2011)
