Banjo influence:
Living here in DC I had a chance to hear Don Reno (after WWII) live and on local tv many times. I don't agree that Earl Scruggs is more accomplished. IMHOP Earl Scruggs has a liquid flowing style, that rolls sweetly and is 'warmer' than Don Reno. Don Reno's style is technically accomplished, but is fiery and staccato, something like Ralph Stanley. His guitar playing had the same quality. I've had a few chances to play with Ralph Stanley at the Washington FF over the years and I agree with Steve above that the emotional content, and the piercing quality of the notes in his playing are 'Old Time'.
On Joe Meadows, he has also taught the banjo and passed along the heritage directly. My son Ian and I appeared in a 'Generations' workshop with Joe and one of his students, his nephew I think, and that boy had received a direct inoculation of old time fiddle from a master.

Now. It's hard for a Bluegrass musician to make a living. Long miles, short pay, and honkytonks are not the easy road. If Earl's wife marketed him well and made it possible for him to make a living, then God Bless her, and, since I haven't met him, I can only say I've heard he is a fine, humble man.

cheers, Chance
