Definition: There are so many different types of definitions, that we could go crazy just defining the word "Definition". When it comes to the word "Jazz", I always explain what the word means to me "personally", as opposed to any universally acceptable definition of the word. Rok's definition was the acceptable "historical" definition up to a point in time; also, there are some jazz musicians who themselves don't like the word, and prefer "Blues Player".
I have stated "my" definition of the word, and by now, Aficionados, should know it; that should be sufficient for "communications", which is what this thread is all about. This thread is not intended for "Publication", which would mean everything has to be technically accurate.
People who post on a regular basis on this thread, "Live jazz"; it's part of their daily life, and we share what we live with one another; it is not written that we should agree. When people who have lived, and are still living a genre of music, that no one seems to know what to call it, they should not be expected to agree.
I appreciate the most recent contributions, and I will listen in depth, and get back to you on the music.
Enjoy the music.
