The AK films from the SD workshops on 1968 are uploaded on Vimeo. The DVD that BTE distributed some years ago is in 4 parts; then there is the Antigone workshop that was found after the DVD was put together. Also the 2 KUSD radio interviews. I have attached the brochure copy from the original release of the films. (Couldn't make that jump from email to this post. Alas.)
I think anyone who studied with AK will find the footage of interest, though I don't think it captures her at her best because the students were (or appear to be) new to her, and its a one-off workshop. Nevertheless, this is about all the footage of her there is, so.....
