Josepp, you make some good points, and I trust your expertise in your analysis of the youthful trends in jazz.

I'm just convinced that this 'quality' problem, the focus on looks, youth, etc. is that much different from previous eras. I grew up in the late 50's and early 60's.....with lots of very young singers named Bobby.   And how old was Eddy Hodges when he sang "I'm Gonna Knock on Your Door".?

I do agree. Esperanza Spalding is certainly one of those rare gems!
