When "Hurt" came on it was phenomenal. There is something indescribable hearing the entire crowd singing along, knowing all the words, coming together as one voice.
The final song ended perfectly, each person stopped playing waved to the crowd and walked off stage. After the four were gone it was just Trent Reznor, playing the keyboard in the spotlight. He stopped, waved and walked off stage. A great image to leave us with.
