Mace, in all honesty, while I enjoy Sketches and Bitches Brew, I think of them as oddities of a sort, so in a way, I don't get them either. In other words, it seems that the others involved (Evans on the former, a multitude on the latter) are more the focus than Miles.
I'm puzzled as to Prince being included on your list, though. That one seems to be pure Miles to me. Oh, well...
