I have little experience shooting live shows with 35mm but nonetheless I would suggest most of the above remains applicable - the critical things still being focus and exposure. You would need a very fast film whilst also dialing back your shutter speed - something like 1/60th can still achieve results and you may get lucky with some creative blurring of the action at even slower speeds.
I know excellent snappers shooting this same scene using 35mm point & shoot cameras which utilize built-in flash to freeze the action and automatic focus to simplify nailing the shot; my wife swears by the Nikon L35af although in my opinion the results are pretty flat.
I love my film cameras but I keep them for more careful, deliberate photo occasions - for the fast pace of rocknroll digital remains supreme!
Hope that helps and enjoy it out there!
Any tips for shooting a show with a 35 film camera ?
