Video Sessions Request

I’m putting out the call for ANYone here who has connections to the music industry, for a strange request: I am seeking raw, unedited footage of composer Elliot Goldenthal, conducting his orchestra. If possible, pertaining to either one of his Batman films. I’ve torn up the interwebs looking for this, to no avail. It’s a tall order, but one that I think is on the uttermost edge of possibility.

I am willing to compensate anyone who is able to provide this to me. Please contact if you have any leads or sources! Thanks so much!
