When it comes to Lang Lang, one of the excuses i always hear about his ridiculous stage antics is that he is like a modern version of Liszt, who supposedly was also famous for being a bit of an attention w*ore.
Now, barring the fact this comparison doesn't excuse anything (as a composer Liszt suffered greatly from his own excesses, his music being a mixed bag for the most part, balancing between great originality but also empty virtuosism and often plain mediocrity), is Lang Lang an actual portrayal of Liszt at all? Everything i read about him seems to point out he was actually a very delicate player, fleeting, almost eerie in his fluidity and refinery (Clara Schumann compared him to a ghost). Is there any evidence he also acted like an angry monkey?
