i get an idea as to what you're after, but this doesn't quite get me there. you might want to look at bob's stuff and check out his gig mentoring thread, to get a better idea about capturing stage lighting dynamically. just my opinion, though...
The yellow of the stage lights is fun and puts the viewer in the "concert mood." Mat's yellow shirt predominates and draws the eye away from his expressive face - perhaps a little selective burning to add some atmosphere and direct the eyes more?
