Brucie, I don't think so.

Too many here don't realize that bluegrass offers just as much improvisation as jazz does. There is plenty of room for extended breaks, and downright jamming in live performances of songs.

I don't know how many times I have heard a lead player be encouraged to "do it again" or a chorus to be refrained "one more time."

The people here who criticize bluegrass I don't believe have seen many concerts or done any much serious jamming with accomplished musicians.
