Rok, it would take a volume of books to answer the questions you ask in regard to music and the generations. Everything, including economics and social structure has to be taken into account; music is not created in a vacuum. When I attempt to answer your questions, after going around like a circle in a spiral, like a wheel within a wheel, and finding myself in a tunnel that leads to a tunnel of it's own, I quit; that's when I throw the four sheets of paper in the can.
Frogman, it feels good to be back. On "Take 6", that's really different; religious lyrics in a jazzy groove, I like that. When I requested new groups of "Afro Blue's" caliber, I didn't realize how difficult that is, now I'm changing it to any time frame.
Rok, Anne Akiko Meyers is new to me, now I'm going to have to get everything she's put out; plus DVD's to gaze upon her foxy face, she's a treat for the eyes as well as the ears.
Enjoy the music.
