I have to "second" the Tierney Sutton recommendations. An earlier poster, last year, mentioned Tierney Sutton's voice as being nasal. I completely disagree with that. Her voice is silky pure. The nassl one, in my opinion, is Stacey Kent.
Paula West is also immensely talented, but unheralded unfortunately.
