All her stuff is wonderful, but Stockfisch is pretty much my favourite label for recording quality.
"Waterfalls" is a simply stunning CD, for recording and music. It is one of my 2 favourite CDs in that regard. You can't go wrong with any of her stuff on that label. If you like that sort of modern folk music, then the compilations "Closer to the Music" on Stockfisch, are a strong recommendation. They include music from Sara, also Alan Taylor, Eugene Ruffulo, David Munyon, all great artists IMHO
