Looking for an acoustic guitar recording..

Leo Kottke and Tony Rice come to mind immediately. Maybe the Three Pickers work by Doc Watson (guitar), Ricky Skaggs (andolin) and Earl Scruggs (banjo). Or for guitar derivative (dobro), anything by Jerry Douglas. This is more in the bluegrass or roots vein then classic country. I am thinking here of excellent music. If by excellent you mean sound quality wise,then any of the Acoustic Music recordings of David Grisman et al have great sonics and great music. More emphasis there on mandolin, but plenty of acoustic guitar as well.

Try the Windham Hill crowd: Alex DeGrassi, Michael Hedges, WIlliam Ackerman. All excellent, each with different styles. LPs and CDs on Ebay. (cheap)

For outstanding finger-style guitar playing, with a bit of celtic, blues and jazz flavoring, any of Martin Simpson's recordings are highly recommended, particularly:
"Live"
"Leaves of Life"
"When I was on Horseback"
