We also shoot it like a sporting event, at the peak of action.inorder not to get a lot of blury pics.Image a jump shot where in the player goes up to shoot, there is a brief second of time before he moves again.Thats the time to fire off your camera.Try to anticipate these peak moments.
Also arm yourself with a wide angle lens and a short tele.Get the entire group and zoom in for individual close ups.
See my Rule of thirds below of Celine Dion in concert.
