I like Lang Lang for his goofyness and because he acts like a clown.
Here's a quote from the PS main page:
and we try to wipe away the elitist attitude towards it.
That's exactly what Lang Lang is doing. He's an amazing virtuoso, and even though I really dislike most of his performances, he still attracts new people to classical music. The only downside is that most people will think every other pianist should 'rape' classical music like Lang Lang does. But then again, who cares! If people like it the way he plays it then he should just keep doing it. I prefer listening to Yundi Li or Rubinstein, but others may dislike these pianists.
I admit that I don’t like what Lang Lang does with his face all the time, either, but you cannot say that he is a bad player.
The same goes for Hyek-Lim. He looks plain silly whenever he plays, but it sounds quite good.
I'd still pick Lang Lang over Cziffra or Horowitz any day, as I absolutely hate those two pianists. Many people consider them to be great pianists, and that doesn't really bother me; it's their choice.
