This is a monster. It's monsterously large, monsterously interesting, and monsterously important. But like most monsters, it can easily be misunderstood. As Mr. Givens, writing just before me has so well expressed, it corrects the sophmoric notion that early jazz was a solely American Black movement.
Unfortunately, it takes a unique record collection to compliment the text as you take in the rich, marvelously written narrative. I have such a collection (both black and white jazz) and it helped emormously to refer to it every few pages. This made reading this book a multi-media tour through my own record collection as well as a reading pleasure. Too bad that CD Mr. Givens mentions was not included with the book -- I would have made the points he makes that much more accessible to people without the music to refer to.
There are many interesting aspects brought up throughout the book. For example, the fact that Sicilians were so important to early jazz, and that white and black jazz, although differing in presentation and performance, evolved together and in relation to one another are two points well and truely made by the book.
As a matter of fact the book is so authoritative that I don't think it can't be successfully critiqued by anyone who does not have years of listening under his belt. I myself went through the early jazz journey, starting with the "jazz is black" point of view when I was in college. A sophomore in fact. We now know that even blues had a white/black evolution as well as jazz. It may be that one has to start at the black is everything perspective to get to the right point of view. I consider people who casually hold that point of view as not completing that journey.
It is also important to note that the book is beautifully written by someone who commands the language as well as the most accomplished novelist.
In any case, Lost Chords is possibly the most important book on jazz written since World War II. I certainly think so.
