The attached shot of my daughter's school rock band is with IS on - but I couldn't use flash and so with ISO 800 and f4 I was only getting a shutterspeed of a 1/10th. The IS has helped to give pretty reasonable sharpness on the drum kit and anything else that isn't moving but of course at a 10th there is motion blur on the band members. Hopefully you have a bit more light than this but f2.8 will be essential and as much ISO as you noise reduction skills can handle.

Incidentally the ageing rocker rear right is the English Master who played with Led Zepplin in his youth.
