I found something in "Vocals" on the jazz critics page; Charenee Wade, Offering: The Music of Gil Scott-Heron and Brian Jackson.
Acman pointed me in that direction and I like it a lot;
https://www.youtube.com/watch?v=sMGME3Bvy9YGil Scott was an idealist who made social commentary in a style that is now called "Rap", but I'm sure he wouldn't want to be called the first rapper. "Rap" is totally disgusting when compared to Gil Scott's social commentary; Rap is low life, but it is what it is, it's what life is about when you sell dope, rap or starve; look at Detroit, Cleveland, and a host of other cities. That's what life is about when all the jobs are shipped out to another country.
Gil Scott was before the working man had come to that state. He was about preventing what we see now. While some were left behind during his time, the "American Dream" was still alive and well; Detroit, Chicago, (even the South Side) and a host of other cities were great places to live; this was in the late 60's and early 70's.
There is a song that paints a picture of a young working man's heaven, it's called "Summer Breeze";
https://www.youtube.com/watch?v=T88fbHOmvRkSee the curtains hangin' in the window
In the evening on a Friday night
A little light a-shinin' through the window
Lets me know everything's all right
Summer breeze makes me feel fine
Blowin' through the jasmine in my mind
Summer breeze makes me feel fine
Blowin' though the jasmine in my mind
See the paper layin' on the sidewalk
A little music from the house next door
So I walk on up to the doorstep
Through the screen and across the floor
If that same young man was living in that same house, he would be living in an uninhabitable crime ridden, dope driven neighborhood; that's what it is today.
