d'Ambrosio is an interesting singer. Very, very quiet and inward -- at the other end of the spectrum from singers with powerhouse voices like Ella or Sarah.
At times, d'Ambrosio reminds me of Irene Kral -- although, to my ears, her artistry isn't quite on Irene's level. (Admittedly, Kral is one of my very favorite singers.)
In any case, here's the The Cove on d'Ambrosio's bandcamp page, if you'd like to give it a listen.
