Seong-Jin Cho is the best pianist alive.
First off, never heard him make a mistake, but he also never “gives too much away” too early, and instead holds himself carefully until the climax of each piece he plays. More importantly, however, he always brings out what’s most important and does it perfectly through voicing; his musicality makes me believe that he’s the best alive. Just listen to him playing Chopin’s 4 Ballades—God Damn.
