Over the months, I watched it three times in person at NYC Film Forum, then another couple of times during the 24h January stream.

It's not AI and it's not just random clips, either. The opening and the ending are always the same. Some parts like the segment on Oblique Strategies and how they shaped the recording of Bowie's Moss Garden were played (almost?) every time. The bit showing the evolution of U2's Pride from a yodeling demo to the finished song played half of the times. Same with the one about his Windows 95 start sound. I think the latter screenings had more examples of generative pixel/glitch art (each of which, presumably, was unique).

My feeling was that segments were divided into categories and/or tags; their selection was like a chef's menu at a restaurant, where you don't know what you'll get, but you can expect that some kind of desserts are always at the end.

Also, I don't think it's exactly true that each performance is different. Between segments, there's some computer output scrolling by and it includes a filename of the next clip. At the start of the movie, the (fake?) filename includes the venue and the date. I didn't stick around for two consecutive shows, but I think they're identical through the day. The 24h streams were different, of course.
