John Coltrane! His standard ballads at the beginning of his career bare virtually no resemblance to where he ended up (which is on Saturn and I love it!)
Most improved players?
I have noticed that some performers have dramatically improved their craft over the years. For example, I believe that John Fogerty really learned to play guitar during those years he took off. Similarly, listening to Marshall Crenshaw's records in sequence demonstrates his growth on acoustic guitar while every time I see Pete Townshend he seems more impressive than before. Any other candidates for this list?
