What is the scene like for the "selection" in Plaszow?

This is a very disturbing scene. The Jews are ushered out of the beds and told to strip naked. The camera zooms in on someone placing a record on a machine and setting a speaker next to it. Upbeat music blasts from the speaker system as the Jews are told to run in circles in front of the officials. Those who are deemed unhealthy and not fit to work are pulled aside to be sent to Auschwitz.
