There are some good suggestions in this thread (and, honestly, some puzzling ones too). I'll try not to repeat previous suggestions here, although I want to thank the posters who recommended Diana Krall: Live in Paris and Muddy Waters: The Folk Singer. Both excellent recordings. The Muddy Waters one is really surprising, given the age and type of music. I didn't expect it to be so engaging. It's not the last word in clarity, but it has a really nice sound to it (even if the vocals have too much reverb/echo).
The first albums that came to my mind are:
• Lyle Lovett: Joshua Judges Ruth
• Chris Isaak: The Baja Sessions
• Phish: Farmhouse
In fact, pretty much all of the albums by these artists are really well recorded.
Also worth noting: I love SRV, but most of his recordings are pretty mediocre. I just discovered that "The Essential Stevie Ray Vaughn and Double Trouble" has much better sounding versions of many songs. It doesn't say "Remastered" but it certainly sounds a lot better to me.
