Off the more usual Jazz & Pop beaten path, if you like Blue Grass, "Alison Krauss + Union Station" Live (preferably a Hi-Def version) is a favorite of mine -- both the CD and Blu-Ray. Alison is an angelic vocalist.
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.
