I just discovered the jazz singer, Nina Simone and am decidedly a fan. I love her songs, the tone color of her amazing rich voice and the variety and diversity of her songs and her voice. Some might recognize her from the movie The Thomas Crown Affair, or if you're older ... from the 60's. She sang the "Sinnerman" song when Thomas was putting the art back and stealing another painting at the end of the movie. Great scene! :) She also sings "Feeling Good" which was sung on American Idol recently (last year, I think). She was most famous from singing at rallies and things in the 60's, very powerful.
Anyway, I just bought her "Compact Jazz" album on I-tunes this morning, yay! :) If you want to her some of her songs just go to You-tube. One of my favorites is "Ne Me quitte pas" ("Don't Leave Me"). So moving. Enjoy!
