Bill Evans and Eddie Gomez, 1966.
I'm guessing this is somewhere in Europe, shot in a television studio for later broadcast. And apparently Evans is traveling without a drummer as Alex, the drummer, doesn't know the set. The film starts out with Evans and Gomez showing Alex the intros, outros, etc., as Alex stands there listening. Then, Gomez shows Alex some sheet music to help with the most challenging of the tunes. And then they film the set. One take through; but they redo the last tune, the most challenging, a couple more times. Then done.
I found it fascinating. Eddie Gomez is just great; and of course Bill Evans is Bill Evans. And Alex looks like he's enjoying playing with these two top tier players. And there are cameras all around the players, moving in close, pulling back, circling around, etc. Sound and camera work are great.
Worth watching even if you're not a jazz fan.
