Nice clips, thanks for the link.
I think it's interesting that some people love someone else's style/sound so much that they go to great lengths to study with, emulate, learn their tunes, and copy their licks in an attempt try to become the next "that guy", or simply as an homage. But coming from the electric bass side, where there are more imitators than original voices, I can wholeheartedly say that I will never be one of these people.
Back to the point, the fact that virtuosic bluegrass has made an underground comeback is awesome!
