Is There a Regressive Bluegrass Music?

There was a kind of regressive bluegrass music in the 60s and 70s, he says. It wasn't about songwriting, it was about playing; that's been key to its survival - making it your own. He calls Chick Korea "a true mentor and a genius cat to be around" The great bluegrass book is full of great songs, but they're of a certain perspective,. They tell the story of a person that grew up in this place. But I think there's a lot of weak bluegrass songs out there -- how can you fake that?
