Hmm, that's an interesting one. I would have to say that the "library footage" referred to would have to be what we see on the TV-screen in Jill's apartment, as she channel-surfs -- with remote in one hand, and a "Major Good-Vibes" in the other!
Cool, Genesis P-Orridge! Psychic TV! I hadn't heard of Monte Cazazza -- looked him up. Wow, yeah. P-Orridge met Cazazza back in 1974, in person, in some sort of Gary Gilmore furore (look it up)(I did,
here). I'll have to examine some of that footage more closely.
By the way, not all of that TV footage is sourced from P-Orridge and Cazazza. I have some intel (more, later) that various tidbits are from San Francisco performance artist, metal sculptor, and mechanical wizard Mark Pauline and his
SRL - Survival Research Labs. And that the titles of several of these clips used were MENACING MACHINE MAYHEM, A SCENIC HARVEST FROM THE KINGDOM OF PAIN, and A BITTER MESSAGE OF HOPELESS GRIEF.
Fun for the whole family!
(I got the Mark Pauline information from a review of HARDWARE written in an out-of-print Cinefantastique, that apparently NO one has, anywhere.

I am in the middle of transcribing it, and plan to have it online soon.)
Anyone know any additional information on the Genesis P-Orridge/Monte Cazazza material?
