Calling all acoustic guitar fans...

If you liked Matthews and Reynolds on the bonus CD, there is a Live 2-CD set of the two of them doing an acoustic concert at Luther College that is one of the most outstanding live-performance CD's out there.

I love acoustic guitar. Here are just a few suggestions without benefit of having read all the responses here (so pardon the redundancies):

Rory Block, "When a Woman gets the Blues" (many of her others are quite wonderful too)
Patty Larkin, "A Go-Go"
Patty Griffen, "Living with Ghosts" & "1000 Kisses"
"The Slide Guitar: Bottles, Knives and Steel" (part of the excellent "Roots&Blues" collection)
Definitely Muddy Waters Folk Singer
If you like acoustic Jazz guitar this one is a truly astounding recording that was on Stereophiles Recordings to Die-For list. It has a very improvisational sound to it.....not for everyone I'd imagine: Marc Ducret, "Detail"

Marco

I would add Nick Drake to any acoustic guitar list.
Start off with one of his compilations.

On another post I recommended Doc Watson. He plays bluegrass and country blues. Absolutely fantastic. All his stuff that I've got, "Memories", "Trouble in mind", and "live on stage" to name a few have great music and sound. Essential!!!! His stuff with his late son Merle is the best.

Here's a few other goodies that haven't been mentioned yet:

Friday Night in San Francisco--DiMeola, McLaughlin, DeLucia.

Train A Comin'--Steve Earle

You? Me? Us?--Richard Thompson (the nude disc)

Quah--Jorma Kaukonen

Another Stoney Evening--David Crosby/Graham Nash

Mijknarf: Acoustic guitar sounds outstanding on my system, too. So do jazz and chamber music. It seems the "simpler" (it terms of ensemble size), the better.

I disagree with one post saying that Leo Kottke was boring. Listen to his first album ("Six and Twelve String Guitar") and tell me, honestly, that it's boring. It's amazing. Glad to see a recommendation for the great, late-departed Michael Hedges. I personally prefer "Breakfast in the Field," but any of his are worth obtaining.

If you like the John Mclaughlin style, then "My Goals Beyond" is a must, as is his acoustic album with Santana.

I'm not sure if you were looking primarily for recordings of well-played music, or for well-recorded/engineered CDs.
