Hmm, reading my answer back, it sounded a bit weird. When I say aesthetics, I mean all the extra stuff i.e. fireworks, a second stage etc etc.

Yes, it is my own wording. If I go to a concert I ain't going to see fireworks, or some guy running around, or to look at a second stage, or a laser show, or anything extra like that. I'm going to hear the music.

For example, if Jon does more running around than he naturally he does, he might get out of breath and concentrate less on the music, and I'd rather hear a near to perfect performance rather than get all these extras. It's just my opinion.
