Norah Jones (start with Cold Cold Heart), Caro Emerald (I really like Stuck, but there are many) Go old school, Little Feat (Mercenary Territory is a favorite of mine) You might like Mazzy Star (start with Fade into you)
Now I listen to many others, The Dead South, Nathanial Rateliff and the Night Sweats, and Devil Doll of late (Great range, try Why and then listen to Heart shaped Crush. So different, so good)
