**** Jazz is not disappearing. It is progressing. ****
Exactly! Although, I might change “progressing” to “evolving”. Whether it is progress or not can be very subjective. Jazz WILL evolve as this is the nature of the “beast”. It always builds on what came before stylistically; hence my question to the OP as to what he considers “traditional” Jazz. Searching for examples of traditional Jazz performed (recorded) in the present will surely disappoint, as the best examples of traditional Jazz are almost always from the past. The best Jazz from the present will be different stylistically; an evolution of the traditional.
**** Like many, for me most jazz is noodling (thank you FZ). ****
Noodling?! Good Jazz (obviously, like any genre, not all is good) is an incredible musical feat. Spontaneous composition (improvisation) of the highest order.
