Christoph Eschenbach Piano Master Class -Yuval Chen 

I am honored to hear great lesson.great student.great accompaniment.

If you are going to the trouble to make a video of such a masterclass, the instructor, Maestro Eschenbach, should have a lavalier mic so viewers can hear his advice and teaching clearly.

Christoph doesn't seem to give a damn whether we hear him or not! Others use a microphone...

Too bad we can't hear a thing.
