These are the Signs from my favorite Music Video, Swan Meat.
There was a Lyric that says "Are you not?".
I'm pretty sure there was sign says "The black Stuff is coming"
and it means the black Stuff was pure evil to change
into a Cobra Form to a Demon Monster in order to devour the Creature Child like Sergei.
And finally, there was another sign says "Here we go"
before Sergei ran up the Stairs to the Top of the Roof of the Tower.
