A Few things I would have liked to have known: Although it is stated that Sonny Rollins is the author which would lead you to believe that Rollins himself was doing the "step by step breakdown of the sax styles and techniques of a jazz giant", the short but often interesting analyses were done by someone from Artemis Music Ltd. It seems that Rollins' authoring refers to the music alone most of which is faithfully reproduced but in a somewhat shorter rendition.
