Silly question but am I the only one that seems to think the director is infatuated with the Asian's violinist's coif?
I agree, his hair does look strange. I'm sure you probably care more than he does. He's an artist.
As for this violinist being a focal point in particular, well, he's the concertmaster for the performance.
I remember the yawn too. At least he wasn't snoring like an old man, because trust me, I've heard them while sitting in large concert halls.
I also remember hearing a cell phone going off, loudly, twice, and the ring was the E major Bach Partita for violin (prelude), and it belonged to a famous artist sitting in the audience.
