Another new female vocal to try out is Jenna Mammina. She has an album called Close Your Eyes which is available in high resolution FLAC, DSD, etc. and all the high res formats.
I think she sounds a lot like Norah Jones but you will hear from the album a wide variety of songs with very good instrumental backing from piano to sax, etc. Definitely one for a Friday night with a glass of red wine!
