Michael, That's a really good point. Bluegrass, in 1945, was to country music what beebop was to swing (or dixieland to early jazz). Interestingly, they both (bluegrass and beebop) came into being at about the same time.

Of course today, country is to bluegrass as Kenney G. is to Miles or Diz or Bird.

Cheers,
