I think the point is not that Miles and Ella aren’t world and genre changing but that we don’t have the intimate footage of them working.

I watched the Miles Davis documentary on Netflix recently and it was great. Well worth the time.

Lots of still photos of him working and lots of interviews with him and people close to him.

What it lacked though was behind the scenes footage with his musicians, producers and studio engineers.

We’re told stories about Miles at his best, and worst, but we’re not shown them happening.
