Scary Piano

Scary Piano is a screamer video released in 2014 from an unknown source.

It starts out with a text showing that there is a subliminal message in a composer's new song for their horror soundtrack. Pretty soon it shows a man a studio playing piano. Then suddenly after playing for a while, suddenly a woman wearing a scary and bloody zombie mask jumps up screaming, and shaking her head lightly.
