Ephemera:  if you had blinked, you'd have
Missed it.  All the doors blew open briefly,
And the blacks behind them boiled out.  
You could have seen the paintings, heard
The music.  It was everywhere, a tidal wave
Of joyous sound.  It couldn't last.  The cops
Arrived.  The music became harsh and bitter.  
Judges' gavels hammered down, and all
The blacks were forced inside.  The doors
Were locked again.
