Picture of NeXTCube Computer debut?

Please anyone has pictures or maybe a video of the first NeXT Cube computer presentation at the Davies Symphony Hall, San Francisco, October 12, 1988?

I would like to see the duet between the Cube and the Violinist, showing the Cube playing high res audio.

Many thanks in advance.

I have never seen a video of the actual introduction of the NeXT Computer.

the only one I know of is this: https://youtu.be/hziXRNZBrH0

but it looks like there must be a video of the event somewhere. see here, just a few seconds.
