Artists that use the same song structure...

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.

"Bluegrass is full of spectacular guitarists."
And vocalists- Alison Krauss being only the most well known; there's also EmmyLou Harris and Dolly Parton (don't laugh, listen to some of her real bluegrass stuff).
As for players, how about Mark O'Connor or Jay Unger on the violin, David Grisman on Mandolin or Bela Fleck on banjo. World class musicianship.

And not to nit-pick Martykl, but Jerry Douglass is most well known as the absolute premier dobro player in the known universe. And yes, I know some may say that a dobro is just a guitar laid across someone's lap.

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.

Martykl- I should know better than to criticize someone w the good taste to recognize Mr. Douglas' skill.

Schubert- The people who laugh at Dolly do so, imo, by judging her w their eyes, not their ears. Although I will admit that when she goes too Nashville/Vegas, the whole package can be a bit over the top.
