Some people I see - people who do more or less have prerecorded tracks - their persona is such that the visual side of just them is way more important and multi-dimensional. Me, I'm boring to look at.
I don't judge people who just hit "play," but I would judge myself if I did that. I wouldn't feel like I was earning my money, I'd feel like I was putting one over on people. I have to play the notes.
