Watch the threshold from the back of the room
technique — attributed to David Landgraf
Landgraf's habit is to stand at the back near the entrance as guests arrive. He is not greeting. He is reading the room as it forms. Phones lifting, conversations softening, pace adjusting are the diagnostic signals that decide what the rest of the night needs.
"At the back of the room stood David Landgraf, watching the entrance."
