Ted Gioia,recently published an outstanding book entitled "Delta Blues".
Here is a
link on Amazon.
I have perused most of the books out there on the subject,and this one is by far the best to date.Not only is the information great,but Gioia's style and delivery make it a very enjoyable read.
Most of the related web sites really only scratch the surface,and most simply regurgitate the same old,same old thing.
Ted Gioia,also did a radio program with NPR,recently talking about the new book.I don't know if there is some way to archivally listen to it? But it would be worth a shot to search around to see.
Anyone serious about the Blues,should pick up a copy of this book.
Good luck on the report!
