I love Sara K, she is under appreciated and the German label she now records for, Stockfisch, is under appreciated too. I have'nt found a bad Stockfisch recording yet and some great artists on the label, along with Sara K, including David Munyon, Paul Stephenson, Mike Silver, Alan Taylor and Eugene Ruffulo. They are all worth exploring, in my opinion.
The best recording I have in any medium, is Waterfalls on basic CD. One of those discs you only have to hear the first 2 bars of the first track, to know you are in for a treat.
