In my opinion, there WAS NO "Bluegrass Music" until Earl Scruggs came to
town (Nashville). Prior to Earl walking on the Grand Ole Opry stage and
hitting his first note, Bill Monroe played "Hillbilly" music. From the
instant he plucked that first note and forever after, Bill Monroe played
"Bluegrass Music".
Some who are not so "pro-Scruggs" play "what if" games, replacing Earl
Scruggs with Don Reno, Rudy Lyle, etc., and they claim that any banjer
picker at that time would have had the same impact. Play all you want, but
there is only ONE history. And, the man who WAS there was Earl Scruggs---end
of story.
Further, there are those on other newsgroups that regularly say, "You cannot
play Bluegrass without the 5-string banjo." Many in here will disagree, but
for me, if you have a fiddle, mandolin, bass, and a guitar---but no banjo,
it ain't Bluegrass. It IS a derivation for sure, but it ain't Bluegrass.
Then again, I'm prejudice.
