I can imagine that you have different qualifications for jazz music in mind as expressed in my collection
As I divide my collection in core jazz - mainly bebop from the fourties an fifties, classical - jazz, like by Stuart McKay, and fusion, you surely can come up with New Orleans, or even Dixieland as 'the real jazz'.
Well the latter - Dixieland - is not my cup of tea, somehow I cannot feel much sympathy for it. To me it sounds like it deliberately wants to make jazz music ridiculous. Perhaps I do not grasp the euphoric state it always seems to be in?
Fusion in which the jazz component clearly dominates - I mean jazz with that real jazzy groove - is also acceptable for me to reckon to Jazz.
You see, I've a hard time defining what jazz is.
Please find out yourself what I mean.
Stuart McKay - Fagotte gavotte
(this is jazz on the edge of classical music)
Airto Moreira - Wake Up Song
With the fabulous Wayne Shorter on soprano sax and Herbie Hancock on synthesizer
