ok, here is my personal take on lang lang, and my view on this debate in general.
first of all, i didnt like the interpretation. i dont like a lot of lang lang's interps, but something keeps drawing me into watching and listening to him. i personally think that we, here, are very wound up by what we think is piano playing, performing and interpreting, and we forget that music is entertainment aswell as an art. why do you think so many people see lang lang and go mad? its simply because he is a show man. whether he is fake is a whole other debate, but he does it and he is able to create a great effect when on stage. i dont want it to sound like the term 'jealousy', but i think the majority of people dont accept him here because we are all questioning where we are going with piano, why we are not famous, whether we will be, and also, why is lang lang famous etc. this is the kind of area where i think the SDC are a good example, because they have a good grasp on the entertainment side of piano, primary example being their interest in speed.
people like Gavrilov, we all know he has huge pianistic ability, but he performs as if the world is coming to an end, but people love it. i love it.
thats my two cents on this topic.
