Artists that use the same song structure...

I once heard a 3 sheets to the wind Roy Clark, who could play anything written for guitar , answer why such a skilled musician as he played and excelled in country.
His reply" Because it takes a real musician to play out-of-tune ALL the time " .

Czarivey,

Doc Watson was a wonderful player, but Bluegrass is full of spectacular guitarists. Check out Jerry Douglass (primary guitarist for Alison Krauss and Union Station) or Tony Rice or Bryan Sutton, among many, many others. I understand that you may find the general tonality of the genre off-putting, but there's wonderful playing talent shot throughout the bluegrass catalog. You may not find it worth the effort to acclimate to the form, but - if you do - you may be pleasantly surprised by what awaits you.

Swamp, why would anyone laugh at Dolly's voice ?
She has a real-deal high-lonesome beautiful voice !

Swamp,

Your point is taken, but a dobro is actually just one brand of resonator guitar. Like "Kleenex", I guess that it has become synonymous with the product type and the resonator is very often considered its own instrument separate from the guitar. Depending on the day of the week (or time of the day), I might do that myself. However, in this particular post, I was including Douglass in the broader class of guitarists. I understand those who'd put him in the separate class of players, but it's essentially a semantic distinction at the end of the day. Probably a little sloppy on my part, tho.
