Jazz music fans, ever seen "Charles Mingus Sextet" video? how is the quality of the tape?

Question

I'm sure the music is great, BUT...

Is the quality of the recording good, regarding:
picture quality,
sound quality,
is it filmed well,
how many camera angles (just one form the crowd, or a team of cameramen).
Is the camera angle constantly being changed, or does it focus on someone for a little while?

I was thinking of buying the viedeo, but I am reluctant because I'm unaware of the quality of the recording. Any comments are very much appreciated. Thank you.

Answer 1

i haven't.
