I recommend this book if you want lots of information on popular music in America during the 19th Century. I can't recommend it as a biography of Stephen Foster.
I was interested in the life story of Stephen Foster. Apparently, the author was more interested in the social and musical forces at play during Foster's lifetime. These are important to the story, to be sure, and the subtitle mentions them. However, it would be more honest to place Stephen Foster's name in the subtitle last, not first, as he does not occupy the center of interest in this book.
Here's what you get: Stephen Foster is born. Twenty pages about blackface minstrel show music, including lyrics, musician biographies, sales receipts. Stephen Foster goes to school. Thirty pages on how much actual African-American melody and lyric made it into the minstrel shows. Stephen Foster gets married. Forty pages on the build-up to the Civil War. It's very difficult to go back and find the pages that talk about Stephen Foster! I found out almost as much about Frederick Douglass.
This book reminded me of a long biography I read on Elvis Presley. In both books, a white musician was influenced--directly and indirectly--by the music of African Americans. For some reason, this phenomenon merits endless analysis. Again, it's an important point in both cases, but I think we do artists a disservice if we over-analyze their influences. At some point, I appreciate Stephen Foster's music for itself, as he wrote it. I credit him with crafting it, and I'd like to know more about the man, less about the century.
