I quite understand your apprehension and I think I know which recent threads you might be referring to, and the biggest culprit.

And, in case you think I was trying to score points forget it. I was just fortunate to work and be in a position where I could get to meet and know a number of blues artists. It is my opinion that most of the more well known of them took about twenty or more years to become an "overnight success".
As is suggested by Tunesmith above, Rush did appear to be somewhat unreliable and difficult to deal with. Which was a great pity.

If you don't already know the work of Magic Sam, I recommend his 1956 recordings on Cobra the same label as Rush around the same time. He also did a storming live recording of "Sweet Home Chicago" at an outdoor blues festival. Off the top of my head I recall it being Ann Arbour. Sadly he died very young.
