You'd be giving up some focal range but I'm sure you're aware of that.
One thing to consider, the VR lens will help camera shake but if you're shooting a bunch of moving objects, you're still going to need a fast shutter, or they'll still be blurry. You might be able to get a sharp picture shooting at 1/6 a second, but if the bass player is pogoing up and down, he's still going to be a blur, the background will be sharp though.
