Great suggestions so far. Since you don't suggest a specific style or genre, I'll just do as others do and ad a few names I have yet to read, but are worthy of the list (sorry if I missed them as I haven't read all the responses yet):

Rory Block, When a Woman Gets the Blues
Kelly Joe Phelps (a master - pick anything...I like "Shine-eyed Mr. Zen")
Dave Matthews & Tim Reynolds Live at Luther College
Joe Pass, "Way Out West" & "Virtuoso"
Chris Whitley, "Living with the Law"
Marc Ducret, "Detail"

Nils Lofgren - Acoustic Live

Small venue, great music, superb recording and, of course, Nils.

I can't believe no one has yet put on

Gino D'Aurio Flamenco Passion of XRCD24!

Not only is this guy an amazing guitarist, this is one of the best sounding red book CD's I have ever heard. If you don't believe me, go buy it and give it a listen, you won't be disappointed!

I wish I was flush right now, great selection gentlemen.
