Blind Tastings Are Bunk (Or Not?)

[DonRocks]

I played this video for Sasha K last night, blind (i.e., he wasn't allowed to look), and asked him to guess who was playing:

He said, "this sounds like Argerich."

My response, "Why do you say that?"

"Because it's technically perfect but flippant in passages."

WTF?!

[DrXmus]

Are both Argerich and Kissin flippant? Is one more flippant than the other? Do they ever out-flippant each other during performances? If it's four hands at a piano, could Argerich's left hand be flippant and his right hand be more serious? Does it ever become overly-flippant?

If you'd asked me who was playing, I would've responded "a piano player". Maybe I would've said "two" but I can't swear to that.
