Having seizure like activity seems to be in style for a modern pianist. Matsuev reminds me of Gilels in that sense, minimal upper body movement. I totally agree with jim about Mitsuko, quite distasteful. As for Khatia Buniatishvili, I don't think she's even in the same universe with Matsuev. All these young Russian women get on stage half naked and get praised for their "technique". How about Lola Astanova? Nearly a million views on youtube. Check out this talent
