This set was the only one they allowed photography at. #cobra#johnzorn#zornat70#livemusic#sfba never seen group communication like this before. Zorn holding up all kinds of different colored/lettered signs, folks raising their hands, different people wearing headbands at times and seemingly taking over the conductor role. Guess you need a robust communication system with dense music with lots of musicians (3 or 4 more offscreen)
