Try also Barbara Bonney. She and Andreas Scholl do a stupendous duet, of Pergolesi's Stabat Mater. The voices just float......
 
Her rendition of the Pie Jesu in Faure's Requiem is also....divine.

  Janis Joplin and Big Mama Thornton!

Never heard of Big Mama, could you post a couple of her albums so I could pick one up for a listen.

  Never heard of Big Mama, could you post a couple of her albums so I could pick one up for a listen.

I would recommend a few songs: 
Gonna Leave You:                                 https://www.youtube.com/watch?v=02wcw-VJ-iU
Hound Dog and Down Home Shakedown https://www.youtube.com/watch?v=wxoGvBQtjpM
 
For her albuns, you'd have a great start at the Complete Vanguard Recordign, but her whole discography isn't that big, so won't be hard to listen to everything.

Not a fan of Regina Spektor but if somebody is interested in similar style there is Alina Orlova from Lithuania who sings in Lithuanian, English and Russian ( usually all languages combined in her albums which in my opinion plays against her because it messes up target audience). 
 
She has released her third album this year called '88'. You can listen it here. They say that her new album is more electronic while her previous were more acoustic.
