The best acoustic guitar recordings??

Darkstar1 - Thanks for that...totally agree on Pizza Tapes...what a great album, a lot of fun, great story behind it, and great sound quality too.

I will look into Jack Rose...curious. never heard of it.

Also, I would add:

Wynton Marsalis & Willie Nelson. Two Men with the Blues
Buddy Guy/Junior Wells. Alone and Acoustic

Maybe an obvious one, but Muddy Waters , Folk Singer. Fantastic.

You seem to have many suggestions here so not sure if these gentlemen has been recommended already. I will however throw these in the hat:

Bill Frissell, I would try “Unspeakable” for starters as to me this album is definitely more vibrant and less safe than his usual, plus he is using more of the guitar and effects to the advantage of the overall sound. If you like this try some of his other safe albums. 
Also have you listened to any Michael Hedges?

Happy listening,
Chris

Mississippi Fred McDowell "I Do Not Play No Rock&Roll".
Also, his requiem album. No title, just Birth and Death dates.

Almost any direct to disc recordings of acoustic guitar
