I enjoyed both of those last two women.
Duffy Bishop reminded me of Marsha Ball, the Uppity BW and Donna Mae (my aunt). I really enjoyed her music. I listened to Blue Monday.
Nice sites on both of those women because you can listen without a long download.

Irene Sage has a nice sound. I listened to Imagine That, and it's a laid back version of her voice, and then Blue Temple. I liked Blue Temple. It's a jazzy with a whistler.
