Shouldn't it matter more to you how it sounds rather than how it looks?
Don't say that in front of Lang Lang.
If you're going to perform in front of a live audience and be well received by people outside the classical niche then it matters.
I guess you're right, but it's sad and stupid.
Also, the flashier performers get the best groupies. Just ask Liszt.
Liszt was like the Lang Lang of his time
Liszt vs Lang lang...Performer vs prolific composer that changed the face of piano forever
