I do like Patricia Barber and her records are really well recorded! At first I found her interpretations a little lacking in emotion but she has grown on me.
I liked Melody from the start and always enjoy listening to her. Her recording are also very well done and the songs are her own for the most part.
Diana Krall is also a favourite. Although more of an interpreter of songs she manages to make many of them distinctive and her own, In my mind she has continued to grow as an artist. " How Deep is the Ocean" becomes new again with her singing it.
It's hard not to like the energy Holly Cole can bring to a song. Listen to "Montreal Live". Again well recorded but she has many LPs and some are not as strong IMHO.
There is no denying the impressive voice of Eva Cassidy and she is also well recorded. While I do enjoy her, somehow I don't find myself listening to her often.
PB has an awesome Band , they carry the music, also agree on Eva Cassidy , i found out about her music just months before she died ..
