If you are not familiar with her catch Iris Dement on You-tube. Especially, "Sweet is the Melody" and "Mama's Opry". She's not a big name, but I heard her several times on Prainie Home Companion and starting looking around for some of her music. I think she has a great voice, totally different and pure. Probably more like some of the female "country" singers of the 1940s and 50s.
