Try Melody Gardot,Eliane Elias & if you like Billie Holiday,Madeleine Peyroux.I'm also surprised no one mentioned Patricia Barber.I find her smoky sultry voice a perfect match for Highland Single Malt.
Jazz for late night relaxation
Jazz friends; I'd like to expand my knowledge of albums geared toward relaxing in the evening with perhaps my favorite brandy or a cup of hot OJ. My taste is varied and I'll post specifics but I feel Paul Desmond and some of Chet Bakers stuff work very well to put me into pure contentment. Thanks for your thoughts. Pete
