Each of them sounded boring to me after a while. Dinah Washington held singing lessons for many other "stars". As for Melody Gardot - her story is amazing. As teenager she made money riding bicycle to local bars and playing piano - until she got hit by the car and spent whole year in hospital bed. Her whole neurological system was damaged and she could not speak. Doctor in desperation suggested singing and that cured her. The only leftover of the accident is cane and sunglasses for damaged eyes.
