All very good suggestions above.
But for an amazing voice performer that no one has mentioned, or probably heard, check out Chris Webster. Locally famous in Northern California. Quboz has only two of her albums, but a good start!

Looking for good recordings of female vocals I have not yet tried...
Most of my listeing is female vocals and classic Jazz. I have enjoyed current and older female singers. I have most of Billie Holiday through current Diana Krall and Julia Fordham. I enjoy good voices mainly acoustic. It would be helpful if it is music I can sample online. If the backing is mainly loud elctronic I would likely pass. Thanks for your thoughts and experience.
