Zorn Documentary

I just watched it for the first time and I'm curious about one section. There was a group that appeared to be recording in the studio. The only musician I recognized was Ribot. There were at least two percusionists. Ribot swung something on a rope above his head, for reference. I didn't recognize the music, but really liked what I heard. Has it been released? Additionally, there was another group with Ribot, Zorn, and Kenny Wollensen (?) with a keyboardist. Was this an early incarnation of Electric Masada or some other one off group. It didn't sound like Masada, but rather more straight ahead jazz. Zorn was definitely dusting off some of his bop licks. What are people's impressions of the documentary overall? Zach
