The book takes "All the things you are" and re-plots
the chords, but the same harmony is ultimately achieved.
The progression is explained shortly, with notes on
how to vary tempo, and side slipping.
The rest of the pages are specific, tabbed-out runs and phrases to "go with" each chord of the song. It seems as if he's saying..."This needs to be played with this".
This book would be good for the beginner, and may feed them a few ideas in the world of jazz improvisation. But i don't recommend it for experienced jazz athletes.
