I really can't agree with this statement about IS as it applies to concert photography. Any moving subject will require a fast enough shutter speed to eliminate motion blur, and IS does nothing for you but allow you to leave a shutter open longer with less fear of camera shake. IS is a tool that allows you to go the other direction from the direction you need to go for moving subjects.
Faster glass is the only answer, or flash if it's allowed.
It really depends on what kind of shutter speeds you are getting relative to focal length. Yes, if your shutter speed isn't fast enough to stop any subject motion to begin with, IS won't do anything for you. The photos I posted were shot with the 70-200mm f2.8 IS, some of them at 200mm. I would have never been able to hand hold those shots at 1/125, which was fast enough to stop some subject motion. (Not when they were trashing about, but when they were singing into the mic for the chorus, etc...) If I had the non-IS version of that lens, I would not have been able to hand hold the lens at 1/125 and get consistent results. So In this case, IS allowed me to handhold the lens, while the 1/125 shutter speed allowed me to stop some subject motion.

The best suggestion so far. But if you can't use a tripod or monopod, you can at least shoot with slow shutter speed bursts instead of single shots. Rip off 5 or 6 shots on high speed and pick the one that has the least blur. After all, if the lens is moving back and forth there's always an instant when it's still before reversing direction.
This is the same principle as "even a blind pig finds an acorn once in a while".

Yep. I was shooting in burst mode. Usually one of them will be usable. Not sure on the tripod. But that depends on the event and venue I suppose.

The 135L f/2.0 might be a good choice to rent. It would help get you closer to the action. One way to decide is to look at your pics and see what focal length you use the most. I have had all three of the primes at one time or another shooting basketball and volleyball and they all work just fine. 85 f/1.8, 100 f/2.0, 135 f/2.0
Depends on the shutter speeds you are getting. However, gathering from the fact that OP was at f2.8 1/125, that would have been the extra stop he needed...i.e. double the shutter speed or shoot at ISO1600.
That's why I bought my 200L...over a year ago to shoot indoor events, concerts, weddings, etc...Extra stop is a godsend when you are thirsting for any light you can get!
