Which adaptation do you think has surpassed its source material in quality?

In 1995, Dylan described his reaction to hearing Hendrix's version: "It overwhelmed me, really. He had such talent, he could find things inside a song and vigorously develop them. He found things that other people wouldn't think of finding in there. He probably improved upon it by the spaces he was using. I took license with the song from his version, actually, and continue to do it to this day."
