First let me add Keith Jarett to the list, and second I would like to add Chick Corea. As other have stated, I can't believe we have gotten this far into the thread without mention of them.
I just picked up a DVD copy of Miles Electric which includes a live performance recorded the Isle of Wright festival 40 years ago to the day that features Miles and both Keith Jarrett and Chick Corea, as well as Jack DeJohnette (Jack is one of my personal favorite Jazz artist, typically a drummer but he has also played piano on some of his recordings). Sorry for digressing off topic...
