"I'm not aware of any other marketed text that brings together this information in such an effective and accessible way. The depth and quantity of information is such that this text represents a considerable body of work that would take any intermediate or advanced jazz pianist many months to integrate, resulting in a clear and applicable understanding of the basis for the sound of modern jazz".
