John Fahey's Railroad I is a favorite of mine. I agree with Chris on Ry Cooder's Meeting By The River, as well. Also, Muddy Waters Folk Singer is an amazing recording, with lots of great guitar from Muddy and Buddy Guy.
And, while no one would call Charlie Christian's recordings audiophile quality, after the first few bars, you probably won't care.
