Cool fellow musician here 🙂
I have used everything from a RED Scarlet, Komodo, Raptor and now currently (own) a Dragon 6K for my band and others.
I also used a BM Pocket 6K, GH3/4 and a slew of other cameras.
You are at the throes of the lighting.
Best lighting ever was a huge event but that was major production.
Then I leave the camera on for some local dive bars and sometimes you get a shock how good it looks.
Yea its a tough go when you dont have control over lighting.
