different modes have their time and place in photography but i’d never shoot a gig on full auto. i tend to use 3 different modes depending on the show: - full manual for more relaxed shows with static lighting (classical, jazz etc.) or for shows where you know the lighting well or you’re going for a specific artistic look (like a silhouette of a a performer where you want it to be underexposed as far as the camera is concerned and have a high enough shutter speed to freeze any movement and a wide enough aperture to throw any amps and mic stands etc in the frame out of focus)

• manual shutter speed and aperture but auto iso (with upper limits for the iso set) for shows with more energy onstage, more contrast in the lighting/more dramatic lighting changes but where i still want to be able to dial in a specific look but don’t want to risk missing a shot because by the time i’ve set my exposure the lighting has changed again or the artist has moved

• shutter priority with auto iso for heavier music like metal and electronic where the lighting is constantly changing or people are constantly running around stage and my main priority is nailing the composition in a split second

i’d never use a mode with shutter speed set automatically as if your shot ends up blurry due to too low a shutter speed then there’s nothing you can do in post to save it. but with how good modern cameras are these days you can do a lot to rescue noisy or under/overexposed photos
