+1 anything w/ Michael Hedges, Aerial is his classic
+1 Friday Night in San Francisco, saw them live in San Diego, Steve Morse opened on acoustic, then came out for the encore...amazing!
+1 Kottke if you prefer nylon strings, same w/ John Williams (yes, if recorded well) , Andres Segovia
If you like the Spanish influence/flamenco, Ottmar and Carlos Montoya
And no matter what, enjoy the music and the talent! Enjoy!
