Why stand on a silent platform?

My recollection of seeing Rage Against The Machine at Reading Festival 2008.

I remember forcing my way to the front of the crowd.
I remember the cold metal of the barrier digging constantly into my chest.
I remember the warm bodies of the people around me.
I remember the exhausted but excited faces of my best friends next to me. I will always remember them.
I remember hearing chanting and singing, laughing and shouting, talking and whispering.
I remember the darkness falling gradually like a giant black sheet, glowing with tiny delicate stars.
I remember my aching feet and cold ears.
The cold. I remember the cold, starting from my feet and creeping its way upwards.
I remember lights; shining, darting, moving, beautiful.
I remember the feeling of belonging, of unity, of power.
Power. Power. Power.
I remember the entire crowd lifting their fists and raising them in the air.
I remember wanting the moment to last a lifetime.
