There is much to laud and much to criticize about Ken Burns documentary, that which is not explained and should be...
The self-destructive behavior as fmdog44 points out.
They all had to start offering their talent in hillbilly bars, was the drinking, adultery, drug use and chasing women an expected part of their behavior as that is how their audience lived and they decided to act as their audiences did? Was it a persona that became real.
Was it the 2-300 nights spent of the road merely an adopted behavior to cope with their lifestyle?
Yes, rock musicians have the same traits; apparently is a learned behavior to cope (?). It also appears to be a terrible waste.
The females are not know for their drunkenness, but they change spouses like bed sheets.
Is the entertainment field that big a mine field?
Much is made of the quality of the singer's vocal abilities. I find the songs lyric driven, the singer's voices all sound the same.
Yes, there are exception, but the music and lyrics outweigh any vocal artistry.
As Vernon Nobles, a true redneck said, '...that damn waling and moaning is interfering with my drinking."
The only singer that loves money more than the lifestyle is Dolly Parton, she has an open marriage with her spouse,
Oh, Carl, he's down on the farm,...bought a new tractor..." I'm sure she has been involved with her share of males; I'm also sure she never meet a dollar she did not like.
It just seems there is so much to this story of hillbilly singers that is not explored. What has been presented is excellent, but so much is missing.
Scattershooting:
Krisofferson was the darling of the college crowd in 60's. He sings like a frog and knows it, again lyrics outweigh vocal weakness.
Did you see the spot where his mother wrote him a letter, 'You have disgraced this family...please do not contact us again.'
Will have to goggle that
