The transcriptions of some of the greatest barrelhouse and blues pianists such as Jelly Roll Morton, Meade Lux Lewis, Memphis Slim, along with their history are in this music book.
There is also a tantalizing CD of samples of the pieces in the book as played by the great blues pianists. This gives essential information as to how the syncopation and rubato sounds in the hands of the masters. The only problem is that as the snippet gets going, you really want to hear the entire piece and whammo! It's only a few seconds per piece, 12 minutes in all. Why oh why couldn't they put at least a few complete works on the CD?
Other than that quibble, this is a great book for blues piano, though greats such as Roosevelt Sykes are to be found in a companion volume, not in this one.
A must for blues lovers who play keyboard.
