An excellent companion to the Burns series (or vice versa, actually--read this first! It has wurds 'n' stuff!) I gave it four stars only for the one nitpick that, in order to amplify a musical point he would occasionally make some generalizations such as how swing players almost learned to phrase away from the beat, which may be true, but it's difficult to really grasp what he means by such statements without a lot of examples. I get it now, but somehow I can't imagine that Coleman Hawkins, the grand old man of the tenor sax who remained relevant through several cataclysmic changes in style could never grasp bebop phrasing! If nothing else, it's tanatalizing to think of Hawkins as a "harmonic" improviser and Young as a "melodic" improviser, even though I think you can hear both tendencies in them. But it's fun to listen to tenors and think "Hawk or Pres"? The jazz age was indeed an age of titans, and the book kind of leaves you feeling like jazz ran out of steam and there's nothing left. That may be true from the standpoint of innovation; but in terms of what was innovated and preserved on record, there is plenty for the rest of us to discover, study, and dig on our own terms--it's still new to the generations who have yet to discover it. That's because it has now passed to the realm of tradition--"Kansas City born, and growing / You won't believe what [these cats] are blowing!" as Steely Dan put it. Just as traditionalists of another generation played fiddle tunes and ballads, "traditionalists" in ages to come will be playing standards out of the Real Book and still feeling the rush of nailing that perfectly placed flatted fifth.
