Here's a sample from the dimmest concert I've ever been to.
Had to shoot wide open at f/1.8 at ISO 6400 and was still only getting 1/30 second.
Noise reduction settings still the default Lr2.
Turns out though this wasn't even the most challenging part of the night. The headlining band used strobes, images from a projector and light dimming. Wasn't easy keeping up, but I think one approach would be to just focus on one light situation at a time (e.g. shoot for the strobe effects, then shoot for the peak illumination, then the projector light).
