Acman, I want to thank you very much for that link.
I personally knew two Blue Note musicians who had drug problems, and they both suffered the same fate as Tina Brooks in regard to their best work not being released until after they were dead.
Did Blue Note recruit drug addicts because they could easily be taken advantage of?
I am not God, therefore I can not be a judge of men. I don't know what demons caused them to seek relief through drugs, but I do know that once hooked, they needed money to buy drugs because they could not function without them. That causes a catch 22; they could not make money because they needed enough drugs to function on the set. While too much as in the case of "Bird", caused him not to be able to function at times on the set.
Although I'm not God, I am a student of sociology and psychiatry; and I'm aware of the fact that mental anguish can hurt more than physical pain. I don't pretend to know what drove those musicians to use drugs; life is complicated; but that problem opened them up to exploitation.
