It is not resting; attacking from two sides and on two levels: with a permanent high blatant voice and with a nervous detonative strong exclamations. They want something, they're bothersome, anxious, and–in a sense–calculated, mathematical. The end is so frustrating: an unfinished story, an accusation sublimed into nothing.
Yuja Wang is a true virtuoso here. She plays casually as it's not a big deal to be precise and fast. The composition is all along over and the smell is still staying in the head.
