She is one of the main reason I started getting serious about guitar again about 4 years ago. She does such a great job on covers and introducing singer/songwriters that are relatively obscure at the time she first sang their material, think TVZ, Gillian Welch, David Olney. I play a bunch of the songs she covered as well as some of her own material. For a diehard fan I strongly recommend the 4 CD + short DVD set "Songbird", it essentially spans her whole career through the early part of this century. I got mine as a gift shortly after it came out, I thought it was awfully expensive at the time ~$70, but necessary. I see that it is now selling for ~$150 new on Amazon, you should be able to find a used one by hunting for half that. You won't regret it. Never seen her personally, keep hoping she would come to a smaller venue somewhere nearby. She played in KC a few years ago at an outdoor venue, tickets were not outrageous for GA (but were outrageous for decent seating), but I don't like to singers at 0.5 mile distances.

"I'm glad there are a lot of guitar players pursuing technique as diligently as they possibly can, because it leaves this whole other area open to people like me."
