On the piano Shirley Horn was the flipside of Oscar Peterson. Oscar loved all the notes so he used as many as he possibly could find room for. On the other hand, Shirley took away as many as she possibly could and still maintain the melody, and she gave them room to live and grow. Like someone once said, "Shirley Horn was what Diana Krall wants to be when she grows up". Normally I'm not crazy about YouTube background pictures, but the Mucha (I think) is fine.
